What is Red mung bean?
Azuki (red mung bean) is an annual vine widely cultivated throughout East Asia and the Himalayas for its small bean. In East Asian cuisine, the azuki bean is commonly sweetened before eating. In particular, it often is boiled with sugar, resulting in red bean paste ( anko ). Azuki beans commonly are eaten sprouted, or boiled in a hot, tea-like drink.
