Cluster beans, also known as guar beans, are slender, green legumes with a slightly bitter, earthy flavor and a firm texture. Commonly used in Indian cooking, they are rich in dietary fiber and nutrients. Cluster beans are typically chopped and cooked in stir-fries, curries, and dry sabzis, where their bitterness mellows and they absorb spices well, making them a healthy and flavorful vegetable choice.
