Japanese Milk Bread, or Shokupan, is possibly the best version of soft white bread! Known for its milky-sweet taste and pillowy softness, it’s enjoyed daily in Japan as breakfast toast and sandwich bread. If you’ve been searching for the perfect milk bread recipe, you’re in luck today. Here, I’ll show you two different styles: One with a rounded top and one with a flat top.
Growing up in Japan, I ate Japanese milk bread, or what we call shokupan (食パン), as a staple for breakfast. The square-shaped white bread is incredibly soft, fluffy, and super moist, even after toasting! These days, you can find shokupan at Japanese or Asian bakeries and markets. But, I’m here to tell you that there’s nothing like homemade shokupan!
This recipe makes a really delicious loaf. I’ve given this bread to my Japanese and non-Japanese friends, and they all highly approve of the results. I hope you will, too.
Before I begin, I’d like to give you a heads up: Both this blog post and my recipe are long, but for good reasons. It is easy for the beginner home baker to follow along and you’ll find all the tips needed to make the best shokupan.
Precision is required for a successful outcome. Those few grams of liquid or dry ingredients do make a difference. For this recipe, you may need to buy some special kitchen and baking tools that you do not have yet. I’m confident that you’ll fall in love with this bread as I have, and that you’ll find these tools worth purchasing. You may end up making this bread monthly, if not weekly like me!
Now, let’s begin!

What is Japanese Milk Bread?
Called shokupan (食パン), Japanese milk bread is the most ubiquitous type of bread that’s eaten daily in Japan. It’s a Japanese-style Pullman loaf that’s shaped like a square or rectangular block.
It has an exterior golden crust and an interior white crumb that’s light as a cloud and fluffy as cotton! It’s the most tender and moist bread you’ll find.
While I’ve seen Japanese milk bread also referred to as Hokkaido milk bread, the Japanese do not use either of these names and simply call it shokupan, which translates to “eating bread.”
What Does Shokupan Taste Like?
Over the decades, Japanese bakers modified the typical Pullman loaf to appeal to the Japanese palate. As a result, shokupan is at once slightly sweet, buttery, and milky. This delicate balance comes from simple ingredients like white flour, yeast, milk powder (or milk), butter, salt, and sugar. Typically cut into thick slices, its flavor and texture are well suited for anything from breakfast toast to Japanese-style sandwiches.
Two Types of Shokupan
There are two types of shokupan:
- a flat-topped loaf called kakugata shokupan (角型食パン), kaku shokupan (角食パン), or kaku shoku (角食; mainly in Hokkaido); and
- a round-topped loaf called yamagata shokupan (山型食パン), yama shokupan (山食パン), or yama shoku (山食; in Hokkaido).
The round-topped loaf is baked without a lid, which allows it to stretch upward and have a light and soft texture. On the other hand, the flat-topped loaf is baked with a lid, so the evaporation of water is minimal; it has a moist and chewy texture as a result.
The History of Shokupan
Bread itself was first introduced to Japan in 1543 by the Portuguese (hence, we call it pan, which is derived from the Portuguese word pão). However, it wasn’t consumed regularly by the Japanese for centuries.
When Japan underwent modernization in the early Meiji era of the late 1800s, British round-topped white bread (イギリスパン) was first introduced during that time. This bread was called honshoku pan (本食パン), literally meaning “staple food bread,” and was mostly consumed by foreigners. Bakeries started to open in Yokohama (my hometown!) and Kobe, where most foreigners resided.
After World War II, a flat-topped square loaf was introduced by the American Resident Army. The loaf was cut into eight slices and made into sandwiches for stationed soldiers. Japanese bakers gradually adapted this bread to suit Japanese tastes, and shokupan was born. Since then, shokupan has been a big part of Japanese food culture.
My Past Disappointment and Mistakes
I want to share some mistakes from my early days of shokupan making, in case some of you have had or will have similar disappointment.
When I made my first shokupan almost a decade ago, I was so disappointed when my bread came out particularly tiny compared to a regular Japanese loaf! All because I was using a regular American Pullman loaf pan to make shokupan. Even though the pan size difference seems insignificantly small, it does affect the outcome of the bread.
You can see the contrast of the end results below. I made two loaves here—one with the regular Western-style loaf pan and the other with the Japanese loaf pan I’m using now. The square and dotted lines show the area we use for Japanese-style sandwiches.
As you can see, a slice from the regular loaf pan is so small that I could barely make Japanese-style sandwiches with it!
Looking for the right size, I went a bit crazy. I purchased four more loaf pans! I even brought back 1.5 kin Tiger Crown loaf pans from Japan. Unfortunately, none were even close to the authentic shokupan size. Please note that there is no standard for loaf pan sizes in Japan, and every company makes their shokupan mold a different size.
But then, several years ago, my luck changed! That’s when Asai Shoten (浅井商店), the famous kitchen equipment company in Kappabashi, Tokyo, introduced its own line of “Ideal Shokupan Molds (理想の食パン型).” These pans make bread loaves that are really close in size to the shokupan sold in bakeries and supermarkets in Japan.
The bread I baked with her was the best shokupan I ever made. It was unbelievable. Her recipe itself is similar to the recipes I’ve tried making, but the techniques she taught me made such a huge difference!
During my first class with Mariko, I learned two mistakes that I had made early on:
- The KitchenAid Professional Series stand mixer with a spiral hook was the wrong choice. I tried and failed many times to make a loaf of shokupan with this machine. The bowl is too wide on the bottom and the wet shokupan dough doesn’t engage the spiral hook. Last year, I bought a KitchenAid Artisan Series stand mixer (325 watts) and this is the perfect tool for making a loaf of shokupan. Note: It turns out that you can succeed with a Professional Series stand mixer IF you double the rectangular loaf recipe, since there’s enough dough to engage the spiral hook.
- Speed 2 on KitchenAid is the wrong speed. The KitchenAid instruction manual recommends Speed 2 for kneading, but it takes forever to reach the right dough texture. Shokupan dough requires more aggressive kneading to develop gluten. Mariko taught me to use Speed 4 and 6. It was a total game changer.
I also learned that advanced knowledge and the right techniques make a huge difference in the quality of your bread. This is where Mariko comes in. As an experienced bread-making teacher, she can provide detailed insight on how to improve your outcome. I’ve taken Mariko’s class twice so far and I feel like I learned new things in each lesson.
Trust me that you can make pretty good bread following my written recipe below, but with Mariko’s guidance, you can improve your techniques even further. It’s the little things you do that will improve the texture and flavor of your bread.
Where to Buy the Right Japanese Loaf Pan
If you don’t mind that your Japanese milk bread is not a standard Japanese shokupan size, then get this loaf pan with a lid (4.2 in. x 7.7 in. x 4.4 in.) on Amazon. You can still follow my rectangular loaf recipe exactly if you use this size.
But if you really want to make true shokupan at home, then you have to get this 1.5 kin loaf pan (4.7 in. x 7.8 in. x 5.1 in.) and/or this 1 kin loaf pan (4.7 in. x 5.3 in. x 5.1 in.) from Asai Shoten (浅井商店) in Japan.
The loaf size in Japan is measured in “kin (斤),” an old Japanese unit for measuring bread weight. The British-style round-topped bread was 1 pound (450 g) back then and it was called “1 kin.”
Now, how do you get a loaf pan shipped to your home from Japan? I have written an extensive post about Japanese loaf pans and how to order them from Japan.
Tools You Need for Shokupan
If you’ve never baked bread before, you may need to get some new tools. However, these are basic tools that you can use for making any type of bread, and they can be useful additions to your kitchen.
- A Pullman loaf pan—I use both a rectangular loaf pan (4.7 in. x 7.8 in. x 5.1 in.) and a square loaf pan (4.7 in. x 5.3 in. x 5.1 in.)
- KitchenAid Artisan Series (5 QT, 325 watts; I do not recommend the bowl-lift Professional Series with a spiral hook unless you double the rectangular loaf recipe)
- C-dough hook
- Digital kitchen scale* (I use this and LOVE it after trying three other brands)
- Large bowl
- Dough scraper (I use this)
- Rolling pin (I use this)
- Mister (I use this; for round-topped loaf)
- Wire rack
- Bread knife (I use this)
*Precise measurement is extremely important for this recipe; therefore, please weigh your ingredients with a kitchen scale. I strongly discourage using a cup or volume measurement.
From Your Kitchen
- Tea towel
- Plastic wrap
How to Make Japanese Milk Bread
You can make shokupan with very simple ingredients and procedures. However, you need time, proper skill, and an understanding of how yeast bread works. To be completely transparent with you, I’m still learning and I may not know all the answers. So again, I encourage you to take Mariko‘s bread-making classes!
Ingredients You’ll Need
(Baker’s percentages are in parentheses)
- Warm water (71%): 104ºF or 40ºC
- Sugar (6%): I use organic cane sugar from Costco
- Instant yeast (2%): I use Fleischmann’s® bread machine yeast or RapidRise® instant yeast
- Kosher salt (2%)
- Honey (3%): I use a multi-floral and clover honey from Trader Joe’s, but you can use other types
- Bread flour (100%): I use King Arthur bread flour, which is 12.7% protein–a whole point higher than other US brands
- Skim milk powder or nonfat dry milk powder (6%): Skim milk powder and nonfat dry milk are different. Skim milk powder has 34% in protein while nonfat dry milk powder has 18%. In Japan, shokupan is made with skim milk powder. Here in the US, you can only find nonfat dry milk powder and I’ve been using Bob’s Red Mill’s to make shokupan.
- Unsalted butter (7%): I use Kerrygold. Please DO NOT use salted butter
- To substitute active dry yeast for instant yeast: Use 25% more active dry. Proof active yeast by dissolving it in a portion of the warm water (105º-110ºF or 41-43ºC) from the recipe before adding to the rest of the ingredients.
- Use the following yeasts interchangeably: Instant yeast = RapidRise® yeast = quick-rise yeast = bread machine yeast.
- Can I substitute bread flour with all-purpose flour? No, please do not substitute if you want to make a proper shokupan loaf. You will need the higher percentage of protein in bread flour for the dough to rise high enough.
- Vegan milk powder option? I haven’t tried alternatives, but Mariko had tried coconut milk powder and it worked. Avoid soy milk powder as the dough does not rise well.
- Vegan butter option? Please use unsalted vegan butter such as Miyoko’s.
Overview: Bread-Making Steps

- Cool: 3 hours
Four Important Tips to Remember
1. Create a Warm Environment for Your Dough
The optimal temperature for fermenting and proofing bread dough is 86-95°F (30-35°C) degrees. Living in San Francisco where it’s relatively cool all-year round (60-65ºF degrees), I had a challenging time with dough proofing until I got a new oven with a proof setting. However, you can successfully proof your dough without a special oven setting.
To create a warm environment, place a baking pan or dish of boiling water on the lower rack of the oven and place the bowl of dough on the upper rack. With the door closed, the oven stays warm and humid. Sometimes, even with just the light on, it gets nice and warm.
Dough proofed at temperatures lower than 86ºF (30°C) will take longer to ferment or will go dormant. At higher temperatures, the yeast will expand more quickly than the gluten structure. If this happens, it won’t be able to keep up with fermentation and the air bubbles will collapse.
Also, avoid placing your dough in direct sunlight in the summertime as it gets too hot and develops a crust, even though it may seem like a warm location for proofing.
2. Use the Windowpane Test
The more you knead the dough, the stretchier it gets. But how do you know when to stop kneading? That’s where the windowpane test comes in handy. It’s a useful way to check the elasticity of the dough, and here’s how to do it:
- Pull off a small bit of dough. Gently stretch it into a square with your fingers.
- Keep on stretching until it becomes a thin film in the middle.
- Check to see that:
- it’s a super-thin membrane;
- light can pass through; and
- there’s no tearing.
- If you’ve got all 3 points, then the dough passes the windowpane test!
Now you know that your dough is properly kneaded and the gluten is well developed. Dough with the right elasticity can hold gases in while it rises and stretches even more as it expands.
3. Create a Smooth and Taut Surface
When you roll and shape the dough, try to create a smooth, slightly taut skin on the outside (see below).
When you have a smooth, taut skin, the carbon dioxide generated during fermentation will not escape. As a result, the bread becomes plump and voluminous, and the baked shape is beautifully finished.
Try one of these two methods for creating a smooth, taut dough ball:
- Place the dough on a non-floured surface. Place both of your hands behind the dough and drag the dough ball along the surface toward your body. The bottom of the dough sticks to the dry surface, creating tension and tightening the ball. Keep the dough ball upright and don’t allow the top of the dough to roll over as you pull (see this video). Rotate the ball a quarter turn and perform another gentle drag toward your body. Continue rotating and dragging a few more times until the dough is sufficiently taut and uniformly round.
- Using both hands, gently pull the sides of the dough to create tension on the outside and tuck the ends underneath the ball.
4. Gently handle the dough as if it is a baby!
Always handle the dough with slow, gentle movements.
Be careful not to cause unnecessary stress to the dough. You would damage it if you pull or tear the dough while you divide, roll, and shape the dough. With your gentle care, your bread will be even more delicious.
Storing Japanese Milk Bread
Let’s check out the different ways to store your baked and completely cooled shokupan:
- At room temperature: This is the best storage method if you consume the bread within 1-2 days. Put your loaf in this plastic bag and keep it in a cool place out of direct sunlight. I usually cut slices off the loaf as needed. On warm days, consume it within a day or store it in the freezer (make sure to slice first before freezing).
- In the freezer: If you can’t consume your bread within a day or two, freezing is the best choice. The bread can stay fresh for up to 2 weeks. Cut the loaf into slices before freezing. It’s typically recommended to wrap the individual slices in plastic wrap to avoid odor absorption and freezer burn; however, I try to minimize plastic use, so I do not individually wrap in plastic. It’s best to enjoy it soon.
- In the refrigerator: The cold air dries the bread; hence, refrigeration is not the best method.
How to Slice Japanese Milk Bread
It’s very important to wait until the bread is completely cooled before you slice it. Otherwise, the bread will be too soft and difficult to slice neatly.
I use a Nagomi Japan bread knife and it is amazing how easily I can slice bread without any struggle!
If you’d like to know the precise thickness of toast and sandwiches in Japan, the standard square milk bread, or 1 kin shokupan, is sliced into the following thicknesses:
- 4 slices — 3 cm (for toast)
- 5 slices — 2.4 cm (for toast)
- 6 slices — 2 cm (for toast)
- 8 slices — 1.5 cm (for toast)
- 10 slices — 1.2 cm (for sandwiches)
- 12 slices — 1 cm (for sandwiches)
No, I don’t follow these rules and my slices are often uneven!
Best Ways to Enjoy Japanese Milk Bread
- Simple toast: Score the shokupan slice in a pattern (see above) and toast it. Then, place a pat of butter on top! If your bread was frozen, mist some water on the slice and toast it in a preheated oven.
- Ogura Toast: This is Nagoya’s specialty breakfast. Toast a slice of shokupan and top with butter, red bean paste, and whipped cream! YUM!
- Sandwiches: Katsu Sando, Tamago Sando (egg sandwich), Wanpaku Sando, and Fruit Sando.
How long does it take for the bread to rise?
It really depends. Different factors can affect the proofing time of your bread, such as:
- the temperature and humidity of your kitchen;
- the freshness of your yeast; and
- the water temperature.
In a warm kitchen, your dough may proof in 40-60 minutes. It can take 2-3 hours in a cold kitchen. It’s important to create a nice toasty environment for your dough to rise.
How do I get the dough to rise faster?
Find a good spot where it’s nice and warm. Heat rises, so some people proof their dough on top of a running dryer machine or on top of the refrigerator.
My recommendation is to use an oven. Place a baking pan/dish of boiling water on a lower rack and place the bowl with dough on an upper rack. Sometimes even with just the light on, it gets nice and warm.
Why is my dough not rising?
Possibly out of these reasons:
- Your yeast was old. (This has happened to me before!) Yeast is a microorganism and it goes bad. Don’t waste the rest of your ingredients because of old yeast. Make sure to get brand-new yeast (and make sure it’s a good batch from the store!)
- Hot water killed the yeast. Read the instructions on your yeast package. Generally, the warm water temperature should be between 105ºF (40ºC) and 115ºF (46ºC) degrees.
- Too much salt/sugar/flour. Did you measure your ingredient with a kitchen scale?
- The dough was too dry. Did you cover the dough with plastic wrap? If you used a damp towel, did it dry up? The dough should be moist and elastic during proofing. Be careful not to develop a crust on the dough’s surface that will prevent it from rising any further.
- The dough was too cold. The perfect temperature for yeast is around 86-95°F (30-35°C) degrees. See my recommendation above to create a nice warm environment for the dough.
Can I leave my dough to rise overnight?
The short answer is yes you can. However, I highly do not recommend fermenting your dough overnight (12-18 hours), especially if you are not an experienced bread maker.
As I consider myself a not-so-experienced bread maker myself, I am sorry that I won’t be able to troubleshoot your situation if you have issues with overnight fermentation.
If you are going to do overnight bulk fermentation, here are some factors to consider:
- The amount of yeast — You must reduce the amount of yeast, but it’s not clear by how much. Some recipes suggest using 1/3 of the amount of yeast called for in the original recipe.
- The initial bulk fermentation — How long do you leave your dough for the initial bulk fermentation before putting it in the refrigerator? It depends on the temperature, but usually 20-30 minutes.
- The refrigerator temperature — Ideally 39ºF (4ºC).
- Experienced eyes to monitor the progress of your dough and determine what to do based on the condition of the dough.
When you resume your bread making, make sure to allow the dough to return to a temperature of 68ºF (20ºC) degrees or higher, which may take up to an hour. Punch it down and divide the dough to continue. You must use the dough within 24 hours since you start making the dough.
What do you think of the yudane (tangzhong) method?
Both yudane and tangzhong are methods of precooking a small portion of the dough either by cooking or scalding. Cooking the flour causes the starch to gelatinize and this makes the texture of the bread chewy (we call it mochi-mochi texture) compared to regular shokupan. Furthermore, the bread stays fresher and moister for a longer time due to a higher moisture content. However, the dough is stickier and harder to knead and it does not rise as high as in a regular recipe.
The majority of Japanese milk bread recipes in English use the yudane or tangzhong method, so it may seem like that’s how you have to make shokupan. However, it’s not a classic shokupan recipe used by bakeries and home bakers. It’s simply just another way of making shokupan.
To be 100% honest, I love how easy and perfect this recipe is. I actually don’t feel the need to use the yudane or tangzhong method to achieve best results. With the recipe that I’m sharing here, I can be totally spontaneous and finish making a really amazing shokupan in 3.5 hours from start to finish. I truly love that part and I make at least one to two shokupan every week. The yudane or tangzhong method doesn’t fit my lifestyle as a busy working mom.
Can I knead the dough with my hands?
The dough for shokupan is very wet and sticky compared to regular bread dough. You may feel doubtful but you will need to trust that it will work if you continue to knead more. What’s more, kneading this type of dough by hand requires a lot of arm work. For these reasons, shokupan dough is more suitable for kneading with a stand mixer. I shared the helpful link in the recipe card.

Japanese Milk Bread (Shokupan)
For 1 Rectangular Shokupan Loaf (1.5 kin (斤) size)
- 250 g warm water (104ºF or 40ºC)
- 20 g sugar
- 7 g instant yeast (I use Fleischmann’s® bread machine yeast; 1 package of yeast (all types) weighs 7 g; make sure to use all the granules; to substitute active dry for instant yeast, use 25% more active dry; proof active yeast by dissolving it in the warm water from the recipe first until many small bubbles appear)
- 7 g kosher salt (Diamond Crystal; use half for table salt)
- 10 g honey
- 350 g bread flour (King Arthur)
- 20 g skim milk powder or nonfat dry milk powder (Bob’s Red Mill)
- 25 g unsalted butter (room temperature)
- ½ tsp neutral-flavored oil (vegetable, rice bran, canola, etc.) (for greasing the bowl)
- 10 g unsalted butter (room temperature; for greasing the pan; you can use cooking oil spray, but I like the taste of butter around the crust)
For 1 Square Shokupan Loaf (1 kin (斤) size)
- 167 g warm water
- 14 g sugar
- 4.7 g instant yeast
- 4.5 g kosher salt (Diamond Crystal; use half for table salt)
- 7 g honey
- 235 g bread flour
- 14 g skim milk powder or nonfat dry milk powder
- 17 g unsalted butter
Before You Start
- Shokupan Loaf Pans: The rectangular loaf pan is 4.7 in. x 7.8 in. x 5.1 in. (12 cm x 20 cm x 13 cm) and can hold 3100 ml. The square loaf pan is 4.7 in. x 5.3 in. x 5.1 in. (12 cm × 13.5 cm × 13 cm) and can hold 2070 ml. I have written an extensive post about Japanese loaf pans and how to order them from Japan. If you're not particular about the size and shape, you can use this 1 lb loaf pan on Amazon and follow the recipe for the rectangular loaf.
- Stand Mixer: Please note that my instructions below are for a KitchenAid 5-QT Artisan Series stand mixer (325 watts). If you're using a KitchenAid Classic Series mixer, do not double the recipe as the 275-watt motor is not strong enough. If you're using a KitchenAid Professional Series mixer with a spiral hook, you must double the rectangular loaf recipe to succeed, as there won't be enough dough to engage the hook otherwise. With twice the dough, you must knead 1½ times longer at each step (as noted in the instructions). If you have a different brand of stand mixer, follow my steps the best you can to achieve a dough with the correct texture that passes the windowpane test. Please see the blog post for more details.
- Hand Kneading: I hope this video is helpful for the kneading technique to use.
- To Create a Warm Environment for Bulk Fermentation: If your oven has a Proof setting, turn it to 100ºF (38ºC). Tip: If your oven doesn't have a Proof setting, place small baking dishes of boiling water at the four corners on the lower-middle rack. Then, place your dough in a bowl in the center of the rack and close the door. The steam and heat from the boiling water will create a warm environment for bulk fermentation. There is plenty of online information on different ways to proof bread dough, such as using an Instant Pot (use the Yogurt function on Low or use the temperature setting).
To Make the Dough
- Gather all the ingredients. Cut the butter into small cubes (I used a pair of scissors). Precise measurement is extremely important for this recipe; therefore, please weigh your ingredients with a digital kitchen scale. I strongly discourage measuring by volume.
- In a large bowl, combine the warm water, sugar, yeast, honey, and salt.
- Whisk it all together and set aside in a warm place for 10 minutes. You want to see bubbly foam on the surface. If you don’t see any, maybe your yeast is old or the environment is not warm enough; wait another 5 minutes to see if any bubbles develop.
- Meanwhile, combine the bread flour and skim or nonfat dry milk powder in a stand mixer bowl. Mix it together and make a well in the middle of the flour mixture.
- Once you confirm the foamy surface on the yeast mixture, pour it into the well of the flour mixture, scraping every bit of the liquid with a silicone spatula or dough scraper. Then, mix it until combined. Keep this yeast mixture bowl, as you’ll be putting the dough ball in it later.
To Knead the Dough in the Stand Mixer
- Warning: KitchenAid does not recommend kneading dough at settings higher than Speed 2. However, we can’t achieve a perfect texture without kneading aggressively. Hold your stand mixer down with your hand(s) when you’re kneading at Speed 6, and keep an eye on it at all times. Do not walk away. Don’t take this warning lightly, as my instructor’s mixer fell off the countertop onto the kitchen floor twice when she stepped away for just a few seconds. Please use it at your own discretion.
- Set up the stand mixer with a dough hook attachment. Knead the dough on Speed 2 for 2 minutes (or 3 minutes if making double the rectangular loaf recipe using the Professional Series mixer). This is just to get started. The ingredients should be well combined after this step.
- Next, increase the speed and knead the dough on Speed 4 for 4 minutes (6 minutes for double). After 4 (or 6) minutes, stop the mixer. The dough will be smoother than before, yet it should still look a bit rough and bumpy.
- Add the butter cubes to the dough. Knead the dough again on Speed 2 for 2 minutes (3 minutes for double), or until you can no longer see any streaks of butter.
- Then, knead the dough on Speed 4 for 4 minutes (6 minutes for double). While spinning, the dough will stretch and elongate (see the photo below).
- Stop the mixer and check the texture of the dough. It should be a lot smoother, shinier, softer, and thinner when it’s stretched. At this stage, the dough is still attached to the bottom of the mixer bowl.
- Now, knead the dough on Speed 6 for 3 minutes (4½ minutes for double). From here, you MUST hold down your stand mixer with your hand(s) since the machine will shake and move, and it could possibly fall off the countertop onto the floor.
- At this stage, the dough will start pulling away from the bottom of the bowl and eventually become a solid ball shape. The mixer will shake and wobble as the dough bangs around the sides of the bowl. Again, hold your stand mixer to keep it from falling and monitor it at all times.
- Japanese milk bread requires aggressive kneading to get that soft, tender texture. The goal here is to develop the gluten (elasticity) by lengthening and stretching the gluten strands in the dough.
- After kneading on Speed 6, stop the mixer. The dough should look really shiny, silky, soft, and smooth (not sticky). When you lift the dough hook, it should pick up all the dough in one piece, separating easily from the bottom of the bowl.
The Windowpane Test
- Now, it’s time for the windowpane test. Either pull on a part of the dough or tear off a small piece. Hold the dough in both hands and gently pull it into a square with your fingers. It should be very elastic, smooth, and shiny. If it's strong enough to stretch to a super-thin membrane without tearing and light can pass through the center, your dough passes the test. If it doesn’t stretch or it tears too easily, knead it again on Speed 6 for 1-2 minutes and test again.
To Slam and Fold
- Once your dough passed the windowpane test, lightly dust the work surface and your hands with flour to prevent sticking. Scrape the dough from the bowl with the silicone spatula or dough scraper and place it on the work surface. From this point, make sure to keep one smooth surface on your dough ball at all times. My nice smooth surface is currently on the bottom of the dough.
- Now, pick up the dough ball, keeping the smooth side up. Then, slam the smooth side onto the work surface. Bang!
- Then, hold one edge of the dough with your fingers in the 12 o’clock position and fold it over to the other side at the 6 o’clock position, revealing the smooth surface. Now, pick up the dough with the smooth side up.
- Once again, slam the smooth surface of the dough onto the work surface. Bang! Now, pick up the edge of the dough at the 9 o’clock position and fold it over to the opposite side at the 3 o’clock position, revealing the smooth surface. Again, pick up the dough with the smooth side up.
- Repeat this "slam and fold" process 5 times in total. After you slam the dough for the final time, leave the dough on the work surface temporarily, and don’t fold it over yet.
- Take the bowl that you mixed the yeast in and thinly coat it with neutral-flavored oil. Wipe off any excess oil from the bowl and your oily fingers with a paper towel. We do not want a pool of oil in the bowl.
- Finally, go back to the dough and fold it over one last time. Pick it up and pull the edges of the dough from all sides to create a smooth, taut skin. Tuck and pinch the edges underneath to hide them at the bottom. Put the dough ball in the bowl and cover it with plastic.
The First Rise (Bulk Fermentation)
- Let the dough rise for 40 minutes. The dough will become 3 times bigger in size. If you live in a cooler climate, it may take longer (1-1½ hours). I use the Proof setting on my oven at 100ºF (38ºC). Please see the "Before You Start" section of the recipe for my proofing tips.
To Use the Finger Test
- Once the dough has tripled in size, dust some flour on top and use your index finger to poke the middle of the dough. If the hole does not close up, it’s ready. If the dough closes up immediately, proof the dough a little longer.
To Deflate the Dough
- Uncover and invert the dough bowl to release the dough onto your work surface. Using your fingers, gently press down and deflate the dough. Remember to keep one smooth surface on your dough at all times. My smooth surface is currently on the bottom of the dough.
- Collect and press all the edges into the middle, flip the dough, and form a round shape, tucking any loose edges underneath.
To Divide the Dough
- Using a kitchen scale, weigh the dough. Then, divide it into 3 equal pieces with the dough scraper. For a square shokupan loaf, divide it into 2 equal pieces.
- If you have a piece that's bigger than the others, tear off some dough from the edge, keeping its smooth surface intact. Attach the torn dough to the edge of a piece that's smaller than the others.
- Form each piece into a ball with a smooth, taut skin: Hold the dough with the smooth surface on top. Gently pull and tighten the dough down from all sides to create tension on the outside. We want all three dough balls to rise equally, so limit the pulling action to roughly the same for each ball, about 3-4 times total. Tuck and pinch the loose dough at the bottom. Place the dough on the work surface and repeat this process for the rest of pieces. Alternatively, you can place the dough on a non-floured surface. Place both of your hands behind the dough and drag the dough ball along the surface toward your body. The bottom of the dough sticks to the dry surface, creating tension and tightening the ball. Keep the dough ball upright and don't allow the top of the dough to roll over as you pull (see this video). Rotate the ball a quarter turn and perform another gentle drag toward your body. Continue rotating and dragging a few more times until the dough is sufficiently taut and uniformly round.
The Bench Rest
- Cover the dough balls with a damp towel and rest the dough for 15 minutes.
- Meanwhile, grease the pan (and the lid, if you're making flat-topped shokupan) with butter (or cooking oil spray).
To Shape the Dough
- After 15 minutes, take out one dough ball, keeping the rest under the damp towel. Gently handle the dough without stressing it. Dust just enough flour so your dough does not stick to the work surface and rolling pin, but not so much that your dough slides around. As you practice, you will know how much flour is just enough. Next, place the rolling pin in the middle of the dough and press it down. Tip: I learned that it's harder to roll out the dough into a rectangular shape if the work surface is dusted with flour. Therefore, I do not dust any flour on the work surface but dust just enough flour on top of the dough ball. When you flip the dough later, the remaining flour will fall off to the work surface, which is just enough for the dough.
- First, roll out the dough away from you, rolling all the way through the top edge. Rolling releases gas in the dough. Next, roll out the dough toward you, rolling through the edge closest to you. If the dough slides around, you dusted too much flour. Next time, reduce or skip the flour.
- Pick up the dough and flip it over, and then rotate it 90 degrees. It's now laid out in front of you in a horizontal oval shape.
- Press the four corners of the dough to shape the oval into a rectangle. Place the rolling pin in the middle.
- Roll out the dough away from you and then toward you, rolling through all the edges.
- Next, roll out the upper two corners, so they are squared rather than rounded.
- Then, roll out the lower two corners. The dough now should look like a vertical rectangle.
- Make sure the dough is an even thickness from the center to the edges. If the edges are slightly thick or see any air bubbles, use the heel of your hand to press down or pop any bubbles on the edges of the rolled-out dough. The rectangle should be roughly 21 cm x 26 cm (8 in. x 10 in.). Tip: I noticed from my own experience that if I don’t roll out the dough evenly at this stage, it affects the shape when I roll up the dough later.
- Fold the dough in thirds, starting with the right third. Bring the dough to the left one-third line, lightly and gently pressing the edge down so it stays in place. Next, fold the left third of the dough, overlapping the edge of the right third by two-thirds. The edge of the left third should be slightly past the center line. Tip: If the dough sticks to the work surface, gently detach; do not pull or stress the dough.
- Press down and seal this edge with your fingers, from top to bottom. At this stage, the folded dough should have an even thickness. Both the right and left horizontal edges are thicker (puffed up), but the overlapped edges along the center line even out the thickness of the dough.
- Fold down the two upper corners toward the center line, so the top now looks like a triangle tip. Then, tuck the tip down toward you, making sure it is right in the middle.
- Start rolling the dough slowly toward you, gently pulling the dough downward as you roll to create a smooth, taut skin, but don't roll too tightly.
- Keep rolling all the way to the end, making sure the shape of the roll is even. Now, pinch the dough at the edge to seal. Keep the rolled-up dough under the damp towel and repeat this process with the rest of the dough balls. Remember which piece of dough you rolled last.
- Now, place the dough rolls in the shokupan mold, starting with the first two pieces you rolled. Place the first dough roll, seam side down, on one side of the mold. Make sure that 1) the seam is on the bottom, 2) the direction of the swirl goes toward (and not away from) the middle of the pan, and 3) the rolled edge touches the pan's side.
- Now, place the second dough roll on the opposite end of the mold, seam side down. Again, the direction of the swirl should go toward the loaf's center.
- Finally, place the last piece of dough you rolled between the first two, seam side down. The direction of the swirl can go either way. Gently press down on the tops of the rolled dough to make them the same height.
- If you are using the square shokupan loaf pan, two rolls should go in just like the rectangular loaf pan (without the middle rolled dough).
The Final Rise (Proofing) and Oven Preheat
- Cover the mold with plastic and place in a warm environment for 1 hour or until the dough has risen to 80-90% of the height of the mold (see the next step). Tip: For the first 30 minutes, I use the Proof mode of my oven. I then take out the mold and place it in a warm area in the house to finish proofing.When you have 30 minutes of proofing time left, start preheating the oven to 425ºF (220ºC). For a convection oven, reduce the baking temperature by 25ºF (15ºC). Tip: My oven usually preheats in 15 minutes; however, it is very important that the oven is thoroughly preheated, so I plan 30 minutes of preheating time.
- To make a flat-topped shokupan (角型食パン), let the dough rise to 75-80% of the height of the mold. Then, remove the plastic and close the lid. If your proof was a bit too long and you exceed 80%, change to a round-topped shokupan. Tip: Don't force the lid closed on the dough. Even if the lid closes, the dough will continue to rise in the oven and the lid will get stuck.
- To make a round-topped shokupan (山型食パン), let the dough rise to 85-90% of the height of the mold. When the highest point of the dough touches the plastic wrap, it’s ready to bake. Now, remove the plastic and spray the surface of the dough with water (I use this mister). Note: The volume for each shokupan mold is very different. My 90% may not be the same as yours if we use a different mold.
To Bake the Bread
- Set the oven rack to the lower-middle position so there's enough space for the bread to rise during baking, especially if you plan to make a round-topped milk bread. For the flat-topped shokupan, bake at 415ºF (210ºC) for 25-30 minutes (in my oven, it’s 28 minutes). For the round-topped shokupan, bake at 385ºF (195ºC) for 30 minutes. Note that I lower the oven temperature (from the preheating temperature). For a convection oven, reduce the baking temperature by 25ºF (15ºC). For a square loaf, the baking temperature and time should be the same or slightly less.
- If you are baking two loaves at the same time, bake 1-2 minutes longer and make sure to have plenty of space between the pans so heat can circulate. Tip: If the loaf has come out lighter in color, you may also want to increase the oven temperature by 5ºF (2-3ºC) next time.
- When it’s done baking, drop the mold 1-2 times on the work surface (I use a grate on the stovetop) to prevent the shokupan from shrinking. This will let the water vapor in the bread escape. Tip: If water vapor remains in the bread, it will weaken the bread's structure and make it easier to deflate. The sides of the loaf will wilt and bend as well.
- For the flat-topped shokupan, open the lid carefully. If you struggle to remove the lid, close it and drop the shokupan mold one more time. If you still can’t open it, note that you need to stop the second proof earlier next time. Maybe instead of 80%, try 75%.
- Give a few thrusts and let the shokupan slide out of the mold onto a wire rack. After baking, do not wash your Japanese shokupan loaf pan. Simply wipe it off with a paper towel and store it completely dry to prevent rust.
- Let the shokupan cool completely on the wire rack; it may take 2 hours. Do not cut or open the loaf while it’s hot; the steam will escape and the bread will lose moisture. Slice the bread and toast it to enjoy with butter and jam or use untoasted slices for Japanese-style sandwiches.
- If you plan to eat the shokupan within 1 to 2 days, put the whole loaf, completely cooled, in a bag and slice as needed. If you don't consume the shokupan within 2 days, slice and freeze the rest for a month to preserve its quality. If you don't plan to eat the shokupan within the next 2 days, slice and freeze it.
