Japanese Mayonnaise [or Kewpie] vs American: Taste & Nutrition
Mayonnaise, often abbreviated as mayo, is a thick, creamy sauce often used as a condiment. It originates from Mahon; in Spanish Mahonesa or Mayonesa, in Catalan Maionesa.
It is a stable emulsion of oil, egg yolk, and either vinegar or lemon juice, with many options for embellishment with other herbs and spices. Lecithin in the egg yolk is the emulsifier.
Mayonnaise varies in color but is often white, cream, or pale yellow. It may range in texture from that of light cream to thick.

How is Japanese mayonnaise different from Western mayonnaise?
Japanese mayonnaise differs from Western mayonnaise in that it uses only the egg yolk whereas Western mayonnaise uses the whole egg.
It is also made with rice vinegar or apple cider vinegar instead of distilled vinegar.
As a result, the taste is tangier and sweeter with a distinct umami flavor while the texture is richer and smoother.
How is Japanese mayo used?
Japanese mayo can be used just like any other mayo. Here are some ways you can incorporate it in your dishes:
- On sandwiches
- As a dip for fries
- In a potato
- In chicken or egg salad
- In dressings
- In marinades
- As a glaze
- On a bagel with smoked salmon
However, when using it, you should be aware that it can really pack a punch so you might want to reduce the recommended dose.
Why are chefs obsessed with Japanese mayonnaise?
Lately, Japanese mayo has exploded on the culinary scene. People love its distinct umami flavor and many chefs say it’s the best mayonnaise in the world.
They say the taste is due to the levels of MSG in the mayo. However, not all forms of Japanese mayo are made with MSG.
Here are some ways renowned restaurants are using it in their kitchens.
- At Nunu, a new Japanese restaurant in Philadelphia, chefs are using it in the coleslaw they put on top of their katsu sandos.
- Otaku Ramen chef Sarah Gavigan adds Japanese mayo and smoked miso to the breading of her Nashville fried chicken which she puts in her hot chicken buns.
- Ask San Francisco’s Stones Throw chef Halverson what he uses as the secret sauce in his burgers. I’ll give you one guess. He also uses the mayo to bind his tater tots.
- Bar Charley in Washington D.C. dots its spicy Korean BBQ wings with Japanese mayo.
Japanese mayo can also be found zig-zagged across various types of sushi rolls in restaurants all over the country.
Is Japanese mayo healthy?
Japanese mayonnaise has come under fire because it often contains MSG (monosodium glutamate). This is the sodium salt of glutamic acid that is used to give food its umami flavor.
Many believe MSG can cause damage to nerve cells. Others say it produces sensitivities such as headache, numbness, weakness, tingling, and flushing. However, this has never been proven in human scientific studies.
Regardless, you can rest easy because many brands provide MSG-free versions of Japanese mayonnaise.
When making it at home, dashi makes a great substitute.
Is Japanese mayo healthier than regular mayo?

Do you need to refrigerate Japanese mayonnaise?

The sauce has a sweet and sour taste and it is often used in steakhouses as a dip for steak or shrimp. It is made from mayonnaise, tomato paste, paprika, cayenne, garlic powder, onion powder, butter, sugar, water, and salt.
Although it is often associated with Japanese cuisine, yum yum sauce originated in the U.S. and Canada. It can be made with western or Japanese mayo.
Can I use regular mayo instead of Japanese mayo?
If you are making a recipe that calls for Japanese mayo but you don’t have any on hand, regular mayo will do in a pinch.
However, if you really want to give it that flavor, you can add rice wine vinegar, and sugar. (Use ½ tsp. vinegar and 1/8 tsp. sugar for every tbsp. of regular mayo and whisk until dissolved).
It won’t replicate the flavor exactly, but it will get you a lot closer!
Now that you know all there is to know about Japanese mayo, how will you be using it to give your dishes an extra kick?
If you’re looking for mayo with a punch, the Kewpie is a great way to make your favorite dishes more flavorful.
It’s definitely not as bland as Western-style mayo because it contains MSG, egg yolks only, and vinegar for a slight tart taste but it’s really creamy and delicious!
