Although the leaves and shoots are also edible, the starchy tuberous roots are by far the most important product. In some tropical areas, they are a staple food crop. The edible tuberous root is long and tapered, with a smooth skin whose color ranges between purple, red, brown, and beige. Its flesh ranges from beige through yellow, orange, and purple.Sweet potatoes are often served in America on Thanksgiving, and sweet potato pie is also a traditional favorite dish in Southern U.S. cuisine. Sweet potato fries or chips are another common preparation, and baked sweet potatoes are sometimes offered in restaurants as an alternative to baked potatoes.
