Sweet Potato 1 article

The storage root of Ipomoea batatas, sweet potato is botanically distinct from the white potato, which is a tuber. Orange-fleshed types are common, but purple and white varieties also occur; the roots are baked, roasted, mashed, cut into wedges, or fried. Orange flesh contains abundant carotenoid pigments, including beta-carotene. In U.S. grocery language some orange sweet potatoes are called yams, but true yams belong to a different plant group.
