Understanding the Difference Between Sweet Potatoes and Yams

Before we dive into the cooking aspect, it’s essential to understand the difference between sweet potatoes and yams. While both are root vegetables, they belong to different species and have distinct characteristics.

Sweet potatoes (Ipomoea batatas) are native to the Americas and are a type of starchy root vegetable. They are characterized by their sweet, soft flesh and thin, edible skin. Sweet potatoes are rich in vitamins A and C, potassium, and fiber, making them a nutritious addition to any meal.

Yams, on the other hand, are native to Africa and Asia and belong to the Dioscoreaceae family. They are starchy, dry, and have a rough, scaly skin that is often difficult to peel. Yams are also rich in vitamins and minerals, but they have a higher starch content than sweet potatoes, making them drier and starchier.

The Origin of the Confusion

So, why do we often confuse sweet potatoes with yams? The answer lies in history. In the United States, what we commonly refer to as yams are actually sweet potatoes. This confusion started in the 1930s when Louisiana farmers began marketing their sweet potatoes as yams to differentiate them from other sweet potatoes. Today, most “yams” sold in American supermarkets are actually sweet potatoes.
