A simple jar of mayonnaise is a common condiment in fridges all around the world. It is typically served as a dressing, in burgers, with chicken or tuna, and is an afterthought when preparing or serving a meal. But in Japan, mayonnaise can be a main ingredient in such things as cakes, potato chips, on pizzas and in ice cream. Although really, it’s best known for accompanying well known national dishes, but not the mayonnaise that you might know. Japan has put their own twist on it, by adjusting the core ingredient that dramatically changes the mayonnaise, but that’s not the only reason why it’s popular here.
