Chufa, also known as tigernut, is a small tuber that grows underground and is native to Africa and the Mediterranean region. It is not a nut but rather a root vegetable, and it has a slightly sweet, nutty flavor. Chufa is often used to make horchata de chufa, a traditional drink in Spain, where it is blended with water and sweetened. Rich in nutrients, chufa is high in fiber, vitamins, and minerals, making it a healthy addition to various diets. It is also gluten-free and can be consumed raw, roasted, or ground into flour for baking.
