Azuki (adzuki) is a small red bean (Vigna angularis), popular in East Asian cuisine. It is widely used in Japan, Korea, China and other Asian countries. Azuki beans are often used to make sweet pastes, which are an ingredient in many traditional Asian desserts. The use of azuki in sushi is quite unusual, but such non-standard combinations are increasingly being tested. Azuki paste can be an ingredient in a sushi roll. The cooked beans, on the other hand, can be used to garnish the dish.
