Adzuki bean. Small, red and shiny bean with a white scar or hilum on the side. It is good in salads, mixed with other vegetables and also good with other ingredients for stuffing because of its size. These beans are often used in sweet dishes as they have more natural sweetness than other beans and are also the basis of the red bean paste used in dim sum. They are used a great deal in Chinese and Japanese cuisine. The flour is used in confections and puddings in China and Japan.
