What’s in a Name?
- True Yams (Dioscorea): Native to Africa and Asia, true yams have a rough, bark-like skin and a starchy, white or yellow flesh. They are not commonly used in American sweet potato casserole.
- Sweet Potatoes (Ipomoea batatas): Originally from Central and South America, sweet potatoes have a smooth, copper-colored skin and a sweet, orange or purple flesh. They are the primary ingredient in the beloved dish we know as sweet potato casserole.
The Sweet Potato Casserole Debate
The debate over whether sweet potato casserole is made with yams or sweet potatoes is primarily a matter of semantics. The dish is traditionally prepared with orange-fleshed sweet potatoes, which are often labeled as yams in the US. However, true yams are not typically used in this dish.
The Origin of the Confusion
The confusion likely originated in the 19th century when American traders imported true yams from Africa and labeled them as “yams.” However, the sweet potatoes that were already widely cultivated in the US were also referred to as “yams” due to their similar appearance. Over time, the term “yam” became synonymous with sweet potatoes in American culinary parlance.
The Difference in Taste and Texture
Sweet potatoes and true yams have distinct flavors and textures. Sweet potatoes have a naturally sweet and creamy texture, while true yams are starchier and have a more earthy flavor. In sweet potato casserole, the sweetness and creaminess of the sweet potatoes are preferred, which is why they are the traditional ingredient.
