The type of yam used for pounding yam is the African yam which is common in  Africa and some parts of Asia. It is also known as puna yam, true yam or white yam. The texture is rough with brown skin and off-white flesh; its length ranges from that of regular potatoes up to five feet long. Puna yam is a food/cash crop  available all year round unlike other crops that are seasonal. Other varieties of yam include purple yam, wild yam, white guinea yam, Chinese and water yam. African yam is rich in carbohydrates and calories. Although it lacks protein, it can be balanced with egg and sauce. Varieties of soup for pounded yam
