What’s Kewpie Mayonnaise?
Kewpie is the Japanese version of Mayonnaise. The Kewpie mayo is yellow, unlike white western mayo. It is sweeter than western mayo, thinner, and contains apple vinegar and egg yolks.
In sushi, Kewpie mayo is used mainly as an ingredient in the famous “spicy mayo” sauce, or by itself on top of crunchy fried rolls.
