    Although yams and sweet potatoes are both angiosperms (flowering plants), they are not related botanically. Yams are a monocot (a plant having one embryonic seed leaf) and from the Dioscoreaceae or Yam family. Sweet Potatoes, often called ‘yams’, are a dicot (a plant having two embryonic seed leaves) and are from the Convolvulacea or morning glory family.

    Yams

    Yams are closely related to lilies and grasses. Native to Africa and Asia, yams vary in size from that of a small potato to a record 130 pounds (as of 1999). There are over 600 varieties of yams and 95% of these crops are grown in Africa. Compared to sweet potatoes, yams are starchier and drier.

    Sweet Potatoes

    The many varieties of sweet potatoes (Ipomoea batatas) are members of the morning glory family, Convolvulacea. The skin color can range from white to yellow, red, purple or brown. The flesh also ranges in color from white to yellow, orange, or orange-red. Sweet potato varieties are classified as either ‘firm’ or ‘soft’. When cooked, those in the ‘firm’ category remain firm, while ‘soft’ varieties become soft and moist. It is the ‘soft’ varieties that are often labeled as yams in the United States.

    Although the terms are generally used interchangeably, the U.S. Department of Agriculture requires that the label "yam" always be accompanied by "sweetpotato." The following information outlines several differences between sweetpotatoes and yams.

    *******Like most people your guests/family won't know the difference but the result will be different. Keep in mind that a yam is a much softer product and therefore won't require as long a cooking time. Cook too long and you will have mashed results.******

    They are different vegetables. The yam came from Africa and the sweet potato South America. In North America quite often the term "yam" is used instead for sweet potato. They can be similar in taste in texture depending on the type of yam. Generally if the recipe is calling for yams, and it is not an ethnic cookbook they probably mean sweet potato. Both can be used in the same way potatoes are used, but I would experiment with the yam by yourself before serving it to people. It does have a slightly different flavour, if you feel adventurous go with the yam. But if you want familiarity stick with the sweet potato.

    Yes. They are pretty much interchangeable. A sweet potato is a root vegetable that grows in temperate climates with a tan outer skin and sweet orange flesh. A yam is a tuber which grows in tropical climates and has a waxy brown outer skin and sweet orange flesh.
