How to Make Japanese Mayonnaise (Kewpie Mayo) マヨネーズ

Whether you call it Japanese mayonnaise or Kewpie mayo, once you try it, you’d never go back.  Japanese mayo has a rich egg flavor, a tangy and sweeter taste, and is creamier in both color and texture. And just like any other Japanese creations, it scores on the umami factor.

Takoyaki, Okonomiyaki, Karaage, Japanese Potato Salad, or Creamy Sesame Dressing…there is one thing common in these dishes and that is Japanese mayonnaise (マヨネーズ)!  The Japanese loves mayonnaise as a dipping sauce, topping, or seasoning, and you would be surprised how much we use this condiment in Japan.

What is Japanese Mayonnaise?

Whether you call it Japanese mayonnaise or Kewpie mayo, it is definitely a delicious mayonnaise you ever taste. Many JOC readers told me they were not a fan of (western) mayo before, but now a big fan of Japanese mayo.

Kewpie is just one brand of Japanese mayonnaise that became popular worldwide, but all the Japanese mayonnaise is also sold in a plastic squeeze bottle and with a fine tip to for you to make the perfect zigzag pattern on your Okonomiyaki.  Kewpie mayonnaise has a signature Kewpie doll logo on the bottle.

Just like soy sauce, sake, mirin, and miso, Kewpie mayo has been one of the predominant condiments in Japan since it was first introduced to Japan in 1925. In fact, when I was growing up, there were not too many varieties of dressings and we used to eat salad with a dollop of mayo (oh the good old days!).

What Does Japanese Kewpie Mayo Taste Like?

So what is Japanese mayo all about? What differentiates it?

Well, you would first notice it is tangier and sweeter than the western mayo.  The texture is thicker and creamier in both color and texture.

Japanese mayonnaise has a rich egg flavor because only egg yolks are used compared to the western mayo that contains entire egg.  Also, Japanese mayo is typically made with rice vinegar or apple cider vinegar, instead of distilled vinegar.

And just like any other Japanese creations, it scores on the umami factor as it includes a small amount of MSG.

7 Important Tips Before Making Japanese Mayonnaise

Mayonnaise is an emulsion of oil, egg yolk, and vinegar.  Oil and water in the yolk are a mixture of two liquids that normally can’t be combined.

Emulsifying is done by slowly adding one ingredient to another while simultaneously mixing rapidly. This disperses and suspends tiny droplets of one liquid through another.  Proteins and lecithin in the egg yolk serve as emulsifiers.

Here are a few tips you need to know before making Japanese mayo:

1. Use vegetable, canola oil, or grapeseed oil

NEVER use old oil and DO NOT use extra virgin olive oil even though it sounds healthier as it won’t emulsify well.

2. Make sure egg yolk is at room temperature

Molecules in cold egg yolks get separate easily, which makes it less ideal for mixing.

3. Use mustard

Not sure about adding mustard?  It’s not included just for the taste, but also to further stabilize the emulsion as it contains small amounts of lecithin.

4. Use Dashi powder to replace MSG

Kewpie mayo includes MSG (monosodium glutamate), which gives the umami flavor. To substitute, I added dashi to give similar umami flavors as dashi contains umami from kombu and katsuobushi (smoked and dried bonito flakes). Since I didn’t want to add any liquid in emulsifying process, I used MSG-free dashi powder.

5. Remember to pour a thin, steady stream of oil

Adding oil too quickly will keep the two liquids from combining (emulsifying); hence, you want to pour in the oil in a thin and steady stream when combining with the rest of the mixture. 

6. Use a blender, mixer, or food processor

The key to making delicious mayonnaise is how small you make the oil molecules. Store-bought mayonnaise may seem to taste better and lighter and that’s because household blender/mixer/food processor is not as powerful as the commercial ones.

Still, it’s better to use an equipment if you already have one in your kitchen. Using a tool helps to churn out your homemade mayonnaise a lot faster and in a more consistent manner (less arm work too).

7. Use Pasteurized Egg yolk or VERY fresh egg yolk

Using pasteurized eggs can reduce or eliminate the risk of being infected by the salmonella bacteria when preparing recipes that call for raw or uncooked eggs (Roughly 1 egg out of every 20,000 eggs will contain the salmonella).  You can purchase pasteurized eggs or make your own pasteurized eggs if you have an immersion circulator.

Too much work!?  Here’s the shortcut to make Japanese Mayo:

This is the shortcut version of Japanese mayonnaise that I come up with using American mayonnaise.

For 1 cup of American mayonnaise (I use Best Foods/Hellmann’s Mayonnaise), add 2 Tbsp rice vinegar and 1 Tbsp sugar.  And whisk until sugar dissolves.

For 1 Tbsp of American mayonnaise, add 1/2 tsp rice vinegar and 1/8 tsp sugar.  And whisk until sugar dissolves.

Just to be clear, it’s not exactly the same, but this shortcut is something you can quickly put together to replicate the taste of Japanese mayo.

Japanese Mayonnaise (Kewpie Mayo)

Whether you call it Japanese mayonnaise or Kewpie mayo, once you try it, you'd never go back.  Japanese mayo has a rich egg flavor, a tangy and sweeter taste, and is creamier in both color and texture. And just like any other Japanese creations, it scores on the umami factor.

Course: Condiments

Cuisine: Japanese

Keyword: homemade, japanese mayonnaise

Servings: 1 cup

Ingredients

• 1 pasteurized egg yolk at room temperature (See Notes)
• 1 tsp Dijon mustard (See Notes)
• ¾ cup canola oil (¾ cup = 180 ml)
• ½ tsp kosher/sea salt (I use Diamond Crystal; Use half for table salt)
• 1 tsp sugar (I added 2 more tsp at the end, but it's up to your preference)
• ¼ tsp dashi powder
• 1 Tbsp rice vinegar
• 2 tsp fresh lemon juice (roughly ½ lemon)

Instructions

1. Gather all the ingredients (Please note: I doubled the recipe above so that I can take good pictures of step-by-step process and a large jar of mayo as a final product). Make sure pasteurized egg yolk is at room temperature.

   
2. In the food processor or hand mixer or immersion blender, put the egg yolk and mustard and process for 20 seconds.
   
3. With the food processor running, SLOWLY drizzle canola oil (A THIN, STEADY STREAM OF OIL) until about ¼ cup of the oil has been added. The mixture is beginning to thicken and emulsify.
   
4. Add kosher salt, granulated sugar, and dashi powder and give everything a whirl again.
   

5. Continue to add the oil in a thin steady stream until about ¼ cup of the oil has been added.  I use "stir" while adding the oil.

   
6. Finally add the rice vinegar, lemon juice, and the remaining oil and process for an extra 10 seconds.
   

7. Taste the mayonnaise and adjust with salt, sugar (I added 2 more tsp, so I used total 3 tsp), or lemon juice to your liking.

   
8. You can store the mayonnaise in an airtight container for about 4 days in the refrigerator.

Recipe Notes

Pasteurized egg yolk: If you cannot find pasteurized egg, use the best, freshest egg you can find for this recipe.  You can pasteurize your eggs if you have an immersion circulator.  Here's my tutorial.

 

Dijon Mustard: Mustard not only adds flavor but it also helps to keep the mayonnaise stable and emulsify the mixture, reducing the risk of the mayo breaking. I personally consider mustard "not optional" ingredient.
