The term 'West African Staple' refers to two different types of food: yams (4 letters) and YAM (3 letters). Yams are a type of root vegetable that is native to Africa and is widely consumed in West African countries. It is a versatile ingredient that can be boiled, roasted, mashed, or fried. YAM is a type of tuber that is also native to Africa and is a popular source of carbohydrates in West African cuisine. It is often boiled, mashed, or fried. Both yams and YAM are important staples in the diets of many West African people.
