Sis forSweet potato
Scientific name: ipomoea batatas
The sweet potato is the thick tuberous root of a plant native to South America. They are sometimes called a sweet yam, but are not related to the true yam. Sweet potatos have yellow or white flesh and as their name suggests, have a very sweet taste. They can be eaten roasted, mashed, fried or cooked into stews. They are much softer than regular potatoes when they are cooked.
