Yam is a tuber that grows mainly in the tropical and subtropical regions of Africa, Asia, and America. In America, the yam is often confused with the sweet potato. The yam has a flesh that ranges in color from pale white to a deep orange. It can be prepared much like a potato or sweet potato, however, its flesh is less sweet than a sweet potato. Select yams with firm, smooth skins. Store in a cool, dark place and use within 1 week.
For other potato varieties, see baking, boiling, new, red, sweet, and white potatoes.
