Sweet potatoes are large in size with a slight small points on both ends. The long tuber has semi-smooth skin that ranges in color from copper, red-brown, to purple-brown, and is firm with a few shallow markings. Underneath the skin, the dark orange flesh is dense, moist, and fine-grained. When cooked, sweet potatoes develop a tender, soft, and creamy consistency with a sweet and slightly nutty flavor. Sweet potatoes are an excellent source of vitamins C and E and contain iron, fiber, and potassium. The tubers are also a good source of beta-carotene, which is an orange pigment that is converted into vitamin A in the body and helps to protect vision loss and improve the skin.
