Adzuki bean (Wikipedia)

Vigna angularis, also known as the adzuki bean (Japanese: 小豆 (アズキ), azuki, Uncommon アヅキ, adzuki), 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 14 in long) bean. The cultivars most familiar in East Asia have a uniform red color, but there are also white, black, gray, and variously mottled varieties.
