Sweet Potatoes vs. Yams

Sweet potatoes are often mistaken for yams. This began decades ago. Some say it was when the soft varieties of sweet potatoes were first introduced and some say it was when orange fleshed sweet potatoes were introduced. Which ever it was, to distinguish them from each other, producers began to call the new variety yams. This was an English translation of the African word, ‘nyami’. While the U.S. Department of Agriculture now requires sweet potatoes and yams to be labeled in the market, here are a few differences to know about. (Similar characteristics are in italics, while differences are not.)
