Homemade vanilla ice cream reaches its new height with a generous drizzle of soy sauce caramel. An interplay of savory, sweet and creative flavors, this Japanese-inspired ice cream is going to have you come back for more!
Just like Kit Kat, you can find an astonishing array of ice cream flavors in Japan. From matcha green tea to black sesame to Azuki sweet red bean, the choices are distinctively unique and Japanese. So why not flavoring the summer treat with our most important pantry staple – soy sauce?
Yes! Soy sauce. It is yet a mainstream flavor where you can find everywhere in Japan, but soy sauce makers and specialty shops have been surprising their visitors with the intriguing combo.
I was introduced to Soy Sauce Soft Serve when my family visited the Kikkoman factory in Japan.
It was unexpectedly delightful that I knew I wanted to recreate the flavor when I return home. Now that the weather is on our side, this couldn’t be a perfect time. In this recipe, I combined my homemade vanilla ice cream with soy sauce caramel sauce. It’s so good that we almost cry tears of joy after taking the first bite!
Why You’ll Love This Ice Cream
- The combination of vanilla ice cream and soy sauce caramel feels completely indulgent and unbelievably delicious.
- It’s melt-in-your-mouth creamy, savory, and perfectly sweet all at once.
- The umami punch and salty notes of soy sauce cut through all the sweetness of caramel and electrify the palate. It would remind you of salted caramel, only so much better.
Delicious Soy Sauce Caramel Sauce
You’ll need 4 simple ingredients to make this amazing sauce.
- Granulated sugar
- Unsalted Butter
- Heavy whipping cream (heavy cream)
- Soy Sauce
Gluten Soy Sauce
I used Kikkoman gluten-free soy sauce in this recipe. Made from rice, soybeans, and salt and brewed with the same traditional method as its original soy sauce, the gluten-free option is just as delicate and aromatic.
Beyond savory dishes, soy sauce can really work its magic and transform sweets and desserts, drawing out their best quality. That’s the multifaceted role of this Japanese condiment. When pairing it with caramel, soy sauce adds complexity and bumps up the overall buttery characteristic of the sauce.
Give it a try! It’s going to change the way you look at many kitchen condiments and the science of flavorings, just like Miso Butter Cookies!

5 Tips to Read Before Making This Recipe
1. Use 2:1 Ratio for heavy cream and whole milk.
After testing a few ratios, we concluded that the two to one ratio for heavy cream and whole milk to be the best. It’s important to use WHOLE milk, not reduced-fat or non-fat milk. The result gives just the right amount of richness and creaminess.
2. Use egg yolks.
I’ve made egg-free ice cream recipes in the past, but for this recipe, I included egg yolks as they act as the emulsifier, to “glue” all the ingredients together and give the ice cream its smoothness and rich flavor.
3. Use the gelatine (sheet).
Gelatin acts as a stabilizer, to prevent ice crystals from forming, which improves texture and extends the life of the ice cream. The more water in your recipe (e.g. strawberry), the more gelatin needed. But don’t exceed a teaspoon (if using powder) in a quart of ice cream.
Instead of gelatine powder such as Knox, we love using GOLD gelatine sheets. They don’t have any smell so it works great for any recipes that require gelatine.
If you prefer not to use gelatin as a stabilizer, try Agar or Xanthan Gum as an alternative.
4. Scald milk and heavy cream.
It is important to first scald the milk and heavy cream in order to shorten the cooking time before you add in the eggs. If heating cold milk and heavy cream with eggs, there is a higher chance the eggs will curdle and your ice cream will be ruined.
5. Get a cooking thermometer.
You need to scald the milk and heavy cream to 83 °C (181 °F) and cook the custard to 71 °C (160 °F). With a cooking thermometer, there is no guessing involved, and your ice cream making will be stress-free.
I frequently use the Thermapen® Mk4 for cooking Japanese Pork Roast, deep frying Karaage, and making desserts like Matcha Tiramisu that count on accurate temperatures. And I cannot emphasize how important it is to have a reliable thermometer to achieve perfect results. It is literally a life-changer!
Your New Favorite Ice Cream Flavor
Due to the amount of air whipped into ice cream, and a few other factors, store-bought ice cream will generally remain soft when frozen, while homemade ice cream tends to freeze hard for scooping. An easy solution is to take the homemade ice cream out of the freezer 5-10 minutes before serving, so it’s soft enough to scoop.
Homemade vanilla ice cream is truly satisfactory. But if you don’t have an ice maker, you want to do yourself a favor by getting good quality vanilla ice cream. You can choose to swirl the soy sauce caramel into the ice cream, drizzle over, or do both as I did in this recipe.
Sophisticated and fun, this Soy Sauce Caramel Ice Cream is definitely a standout treat for the summer. Serve it as a dessert for your Japanese-theme BBQ cookout.

Soy Sauce Caramel Ice Cream
Video
Ingredients
For Soy Sauce Caramel (yields 1/2 cup or 120 ml)
- ½ cup sugar
- 3 Tbsp unsalted butter
- ¼ cup heavy (whipping) cream
- 2 Tbsp soy sauce (I used Kikkoman Gluten-Free Soy Sauce)
For Vanilla Ice Cream
- 2 cups heavy (whipping) cream
- 1 cup whole milk
- 3 large egg yolks
- ½ cup sugar
- ½ sheet gelatin (1.1 g; or use ½ tsp gelatin powder; [Equation] 1 envelope gelatin powder (0.25 oz, 7 g.) = 1 Tbsp powdered gelatin = 3 sheets GOLD leaf gelatin. One sheet leaf gelatin would correspond to 1 tsp of powdered gelatin.
- ¼ water
- 1 ½ tsp vanilla extract
Instructions
- Gather all the ingredients.
To Make Soy Sauce Caramel
- You can double the recipe but do not increase beyond that because it’s not easy to melt the sugar properly. In a small saucepan, heat ½ cup sugar over medium heat, stirring constantly with a whisk, silicone spatula, or wooden spoon.
- Sugar will form clumps and eventually melt into a thick brown, amber-colored liquid as you continue to stir. Careful not to burn from the splatter.
- Once sugar is completely melted, immediately add 3 Tbsp butter. The caramel will bubble rapidly so take extra cautions not to burn yourself from the splatter.
- Stir the butter into the caramel until it is completely melted. If you notice the butter separating or if the sugar clumped up, remove from heat and vigorously whisk to combine. Keep whisking until it comes back together, even if it takes 3-4 minutes. It will eventually get there. Just keep whisking. Return to heat when it’s combined again.
- Very slowly drizzle in ¼ cup of heavy cream while stirring. Since the heavy cream is colder than the caramel, the mixture will rapidly bubble when added. It will rise in the pan as it boils.
- Turn off and remove from the heat and stir in 2 Tbsp soy sauce.
- Allow it to cool down slightly before use. Caramel thickens as it cools.
- After the caramel cools down, pour it into a glass jar or container. Refrigerate for up to 1 month and freezer for up to 3 months. The caramel solidifies as it cools, but you can reheat in the microwave or on the stove so it becomes liquid again. For the frozen caramel, thaw in the refrigerator or at room temperature, then warm up before using.
To Make Vanilla Ice Cream Mixture
- Cut the gelatin sheet into 1-inch (2.5 cm) pieces and add ¼ cup water to let the gelatin bloom for 10 minutes.
- In a medium saucepan, add 2 cups heavy (whipping) cream and 1 cup whole milk.
- Whisk together and bring it to almost simmering over medium-low heat until small bubbles appear along the edges (but don’t let it boil), about 8-10 minutes. If you have a cooking thermometer, it should be 181 °F or 83 °C.
- In a large bowl, combine sugar and egg yolks (if you are using gelatin powder, add now).
- Whisk together till combine.
- Add a quarter of the milk mixture from the pot into the bowl, while constantly whisking (to prevent the eggs from cooking).
- Then repeat with another quarter of the mixture, while stirring with the plastic spatula.
- Finally, pour everything in the bowl and whisk together. Then pour back the mixture into the pot.
- Drain the water from the gelatin sheet and add it to the mixture.
- Return the pot to the stove and heat on medium-low, stirring constantly to prevent the mixture from sticking to the bottom of the pot.
- Without allowing it to boil, heat for 8-10 minutes, or until the mixture thickens enough to coat the back of a spoon. The cooking thermometer should reach 160 ºF or 71 °C to pasteurize the eggs. Turn heat off and pour the mixture through a fine-mesh strainer into a 4 cup measuring cup or a medium bowl.
- Add the vanilla and stir to combine.
- Prepare a large bowl with ice cubes, and set the measuring cup (or the medium bowl) inside. Stir the mixture occasionally to help cool faster. Once cool (should take about 30 minutes), cover with plastic wrap and place in refrigerator overnight or at least 4 hours.
To Churn Ice Cream
- On the following day (or after 4 hours), set up your ice cream maker according to the instructions. My Cuisinart ice cream maker just broke so I borrowed my friend’s fancy ice cream maker that does not require freezing the bowl in advance. However, many home ice cream freezers have bowls that need to be frozen ahead of time. Don’t skimp on this step! A bowl that isn’t completely frozen will take longer to freeze your ice cream and impact the finished product. If you make homemade ice cream on a regular basis, store your bowl in the freezer once it is clean. It will always be ready for your next batch of ice cream.
- Pour the mixture into the ice cream machine. Make sure not to fill it more than about ⅔ of the way up.
- Start churning. Churning ice cream incorporates air into the finished product while it freezes, so you will need some extra room in your freezer bowl.
- The mixture has been thicker and creamier, about 25-30 minutes.
- Lift up the paddle and remove the ice cream with a (mini) silicone spatula into the ice cream maker bowl.
- Transfer half the ice cream into an airtight glass container (ideally a square or rectangular shape) and flatten the top with the silicone spatula.
- Drizzle generous amount of soy sauce caramel on top.
- Add the rest of the ice cream and flatten it with the silicone spatula.
- Drizzle more caramel sauce on top. Save some for drizzling when serving.
- Cover the lid and put it in the freezer. Set freezer temperature to the coldest setting, so the ice cream freezes faster. Optional: Lay plastic wrap directly on top of ice cream and press down gently to prevent ice crystals from forming on top of the ice cream.
To Serve
- Take the ice cream out of the freezer 5-10 minutes before serving, so it becomes soft enough to scoop. Drizzle extra Soy Sauce Caramel on top if you like.

I just made your matcha ice cream and it is so good!! I want to make vanilla too but can’t use gelatin because I am a vegetarian. Do you think agar agar would be a good substitute? I have had luck replacing gelatin with in in cheesecake before.
Hi Rachel! Thank you for trying Nami’s recipe!
Yes, agar agar can be used as a substitute.🙂
We hope you enjoy the ice cream!
Made this recipe yesterday and it is delicious. I’m making hojicha flavored ice crream today to swirl it on or maybe top it off with. Thank you for this recipe!
Hi Lisa, We are glad to hear you enjoyed Soy Sauce Caramel Ice cream!
Hojicha ice cream sounds delicious too!
Thank you for trying Nami’s recipe!
Nami, thanks for this great recipe. Caramel with soy sauce is awesome. Just one question on caramel: traditionally they don’t stir sugar but leave it to dissolve by itself otherwise caramel will crystallize. I still decided to do caramel exactly as in your recipe- it crystallized but not critically. Some of sugar crystals just sticked to my spoon and turned to stone. And when I added butter, my caramel turned to clots (wasn’t homogenous liquid as in your video). Cream saved the day but some sugar crystals still stayed. What I did wrong? Maybe we shouldn’t stir after all? And what did I do wrong with butter? 😀
Anyways, the taste still was great. Salty caramel on vanilla ice cream is one of the best dessert experiences I have ever had.
Hi Zaur, Thank you very much for trying Nami’s recipe!
We are glad to hear you enjoyed the unique taste of this ice cream but sorry to hear that it had difficulty melting the sugar.
Nami used a whisk to stir the sugar, but please feel free to try the traditional way next time if it works better for you.
In step 3, the sugar must be completely melted, and then add the butter; otherwise, it will be clots.
We hope your next try will be easier than this time.🙂 Thank you very much for sharing your cooking experience with us!
Should you ever find yourself in central Akita-ken, there is a Michi-no-eki along route 46 quite close to Kakunodate that sells soy sauce ice cream cones. They are phenomenal.

Hi Brian! Ah it must be so delicious! Hopefully one day. I’ve been to Akita once when I was in my 20s!!
Hi Nami, I made this ice cream just now. It is super ultra delicious!! Can’t wait to let my nieces have a taste! Thank you for sharing another wonderful recipe 🙂
Hi Nha! Yay!!! That made me so happy! Thank you for your kind feedback. 🙂
Sooooo good (and so easy to make)! I made just the caramel sauce and we drizzled it over vanilla ice cream. Thank you for another amazing, tasty recipe!
Hi J! Glad to hear you liked the recipe! Thank you for your kind feedback. 🙂
I plan to use ヒガマルうすくち (20% reduced sodium). I think that will be OK with this recipe because the flavor is so delicate. My only other choice is Yamasa less sodium shoyu, which has a really strong flavor. I’m really looking forward to making this soon! Thank you for offering such a wide diversity of mouth-watering recipes. I wish you a speedy recovery!
Hi J! That’s okay to use – if the saltiness is not enough, you can add the salt later or sprinkle flake salt etc on top of ice cream/caramel sauce too. 🙂 Thank you so much for well wishes. My sling came off yesterday, and I’m so happy I can use both hands to type! 🙂
I just made this sauce, and it is ENTIRELY amazing. Thank you so much for the recipe, and your puppy is adorable.
Hi Celina! I’m so happy to hear you gave this caramel sauce a try! Thanks for trying this recipe and for your kind feedback. And thanks for your sweet words on Miso. 🙂
Delightful recipe, clear instructions, genius-level use of ingredients! Nami-san, you are the high priestess of great multi-cultural food! Domo arigatou for the inspiration!!
Hi Carolyn! Thank you for your kind words, Carolyn! Hope you enjoy cooking Japanese food at home! 🙂
I don’t have an ice cream maker so won’t be trying the ice cream recipe but I am intrigued by soy sauce caramel and can’t wait to make it. Caramel can be tricky but your instructions, as usual, are excellent.
I love that photo of your children, they look very sweet 🙂
Hi Connie! Hope you enjoy(ed) the soy sauce caramel. We love it and drizzle on vanilla ice cream (store-bought) too. Thank you for your kind words! xoxo
