Generally, in the United States, orange-flesh sweet potatoes are labeled yams while the pale variety, with light yellow skin and flesh, are labeled sweet potatoes. However, vegetables sold as yams in one market may be sold as sweet potatoes in another. Fortunately, yams and sweet potatoes can be used interchangeably, and both are considered superfoods by nutrition experts.
Yams (that is, orange-flesh sweet potatoes) are available year-round, but their peak season is winter. When purchasing, look for small to medium yams that are smooth, firm, and free of soft spots. Store whole, unpeeled yams in a cool, dry place for up to 1 week. Do not refrigerate yams, as they can dry out.
Tip: One pound yams equals about 2 medium yams or 2-3/4 cups cubed.
Yams can be used in many ways. For side dishes, they're often boiled or baked (peeled or unpeeled). They can be added to soups, stews, and braises. Sometimes boiled yams are mashed to serve as a side dish or for use an ingredient in quick breads and pies.
