Yamsas, also known as "yams," are a type of tuber commonly found in Africa, Asia, and the Caribbean. They belong to the Dioscorea genus and are often confused with sweet potatoes, but they have a starchy texture and a more neutral taste. Yams are rich in carbohydrates, vitamins, and minerals, making them a staple food in many cultures. They are typically prepared by boiling, roasting, or frying.
