About

Vigna angularis, also known as the adzuki bean (Japanese: 小豆, Hepburn: azuki), azuki bean, aduki bean, red bean, or red mung bean, is an annual vine widely cultivated throughout East Asia for its small (approximately 5 mm or 1⁄4 in long) bean. The cultivars most familiar in East Asia have a uniform red color, but there are white, black, gray, and variously mottled varieties.

Scientists presume Vigna angularis var. nipponensis is the progenitor.

Uses

In East Asian cuisine, adzuki beans are most commonly sweetened before eating. They are often boiled with sugar to produce red bean paste, a widely used ingredient throughout the region. The paste is sometimes flavored with ingredients such as chestnut and serves as a filling or topping in numerous traditional dishes.
