Ume-Mayo Onigiri

The Ume-Mayo Onigiri (梅マヨおにぎり) is a type of onigiri, a traditional Japanese rice ball, filled with a combination of pickled plums and mayonnaise. The term "Umeboshi" (梅干) in Japanese signifies "pickled plums," originating from "Ume" (梅), which stands for the fruit "plum." When combined with "mayo," the abbreviation for mayonnaise, it creates the delightful flavor combination, "Ume-Mayo", found in this onigiri.
