Savvy eaters know that yams and sweet potatoes are good enough to serve year round. Even so, fall and winter months bring them center stage for holiday sides and accompaniments.
There are many varieties of sweet potatoes, which all come from the morning glory family.
Skin color can range from white and yellow to red, purple and brown. The interior flesh can be white, yellow, orange or even orange-red.
Confusion sets in with our naming of yams versus sweet potatoes. In the United States, we actually produce two types of sweet potatoes, not yams. Most grocers distinguish them as yams and sweets based on their firmness. The two major types: Firm sweet potatoes, which have golden skin and paler flesh and Soft sweet potatoes, which have copper skin and orange flesh (we call them yams).
