Sweet red bean paste, or anko, is a kind of Japanese jam made with azuki beans, a legume grown extensively in East Asia. With a soft texture and a sweetish taste, these beans can be perfectly used for the preparation of jams, preserves and other various types of desserts. In Japan, anko is mainly used as a filling for some typical sweets, such as the famous dorayaki, daifuku (mochi) or taiyaki, sometimes it is also used as a garnish for ice cream.
Easy to make, you will just have to boil the beans in water, add a sugar syrup and blend everything until you get a smooth, homogeneous and super soft cream. Depending on whether the beans are left whole or pureed in cream, there are two different variants: tsubuan with whole legumes and koshiban with pureed ones.
