Adzuki Beans

Also indexed as: Azuki Beans

The adzuki bean holds a place in ceremonial dishes in both Japan and China.

The adzuki bean, sometimes spelled azuki or aduki, is a versatile bean well-loved in Japanese cooking. It holds a place in ceremonial dishes of both Japan and China, where the beans are used to make traditional dumplings at the New Year and for other festive occasions. Adzuki beans are quite small and are usually a deep red color with a sliver of white at the inseam.

Varieties

Adzuki beans belong to the Phaseolus species and are generally categorized in the “red bean” family, although they are less common in the United States than other red beans such as the kidney bean and the small red bean.

Buying and storing tips

Store dried adzuki beans in an airtight container or jar. Look for shiny beans that are richly colored reddish-brown or brownish-purple.

Availability

Adzuki beans are available year-round, dried or canned. They can be found primarily in natural food stores and Asian markets.

Preparation, uses, and tips

Adzuki beans are easy to digest, and although they have a distinctive flavor, they taste less “beany” than many other beans. The preferred cooking method is to soak them in cold water for two to three hours and then simmer them on top of the stove for about an hour and a half. They also cook well in a crockpot or pressure cooker. In Japanese cooking, they are used in desserts in the form of a sweetened paste called an, koshi-an, or tsubushi-an. When adzukis are prepared with rice, the rice takes on a beautiful reddish-purple tint from the beans.
