The adzuki bean is a small, red legume native to East Asia, particularly popular in Japan and China. It is often used in traditional dishes, especially in desserts, where it is cooked with sugar to create sweet pastes. Adzuki beans are known for their slightly sweet flavor and are rich in protein, fiber, and various vitamins and minerals. These beans are typically harvested in late summer and can be found dried or canned in many grocery stores. They are versatile and can be used in both sweet and savory recipes, making them a nutritious addition to a balanced diet.
