anko
Rich in fiber, plant-based protein, and complex carbohydrates from the azuki bean base. Provides iron, potassium, and polyphenol antioxidants, though the added sugar content makes it a calorie-dense condiment rather than a whole-food legume.
About
Anko is a sweetened paste made from azuki beans (Vigna angularis), a small red legume native to East Asia. The beans are cooked until tender, then mashed or ground into a smooth or slightly textured paste and combined with sugar or honey to create a concentrated sweet preparation. The paste ranges in color from deep burgundy to dark brown and has an earthy, mildly sweet flavor with subtle nutty undertones. Traditional Japanese anko is made by cooking dried azuki beans, pressing them through fine sieves to remove the skin (producing *koshi anko*, or smooth paste), or leaving the beans partially intact for a coarser texture (*tsubu anko*, or chunky paste). Regional variations exist across Japan, Korea, and China, each with slightly different sweetness levels and bean-to-sugar ratios.
Culinary Uses
Anko is a fundamental ingredient in Japanese, Korean, and Chinese desserts and confections. It is most famously used as a filling for mochi, daifuku, taiyaki (fish-shaped cakes), dorayaki (red bean pancakes), and various wagashi (traditional sweets). The paste serves both functional and flavoring roles: it provides moisture and sweetness while imparting a distinctive earthy legume character. Anko can be spread on toast, swirled into ice cream, used as a filling for pastries, or eaten as a standalone sweet. In Korea, it appears in bingsu (shaved ice desserts) and various confections. The paste pairs well with subtle flavorings such as matcha, sesame, or yuzu, and contrasts effectively with neutral bases like rice cakes, glutinous rice, and custards.
