When it comes to cooking, many of us assume that yams and sweet potatoes are interchangeable. After all, they’re both starchy, delicious, and often used in similar recipes. However, the truth is that yams and sweet potatoes are not the same thing, and they don’t always cook the same way. In this article, we’ll delve into the differences between yams and sweet potatoes, explore their unique cooking characteristics, and provide you with some valuable tips for preparing these tasty tubers.
What’s the Difference Between Yams and Sweet Potatoes?
Before we dive into the cooking aspect, it’s essential to understand the difference between yams and sweet potatoes. While both are types of root vegetables, they belong to different species and have distinct characteristics.
Yams are a type of starchy vegetable that belongs to the Dioscoreaceae family. They’re native to Africa and Asia and are often larger and starchier than sweet potatoes. Yams have a rough, scaly skin that’s usually brown or black, and their flesh is white, yellow, or purple.
Sweet potatoes, on the other hand, belong to the Convolvulaceae family and are native to the Americas. They’re smaller and sweeter than yams, with a smooth, thin skin that’s often orange, yellow, or white. The flesh of sweet potatoes is typically orange, yellow, or white.
Why the Confusion?
So, why do many people think that yams and sweet potatoes are the same thing? The confusion likely stems from the fact that what Americans commonly call “yams” are actually sweet potatoes. In the United States, sweet potatoes are often labeled as “yams” in grocery stores, which has led to the widespread misconception that they’re interchangeable.
In reality, true yams are not commonly found in American supermarkets. They’re more often found in international or specialty stores, particularly those that cater to African or Asian cuisine.
Cooking Characteristics: Yams vs. Sweet Potatoes
Now that we’ve established the difference between yams and sweet potatoes, let’s explore their unique cooking characteristics.
Yams
Yams are generally starchier and drier than sweet potatoes. They have a higher concentration of starch, which makes them more dense and dry. When cooked, yams tend to be firmer and more crumbly than sweet potatoes.

Sweet Potatoes
Sweet potatoes, on the other hand, are sweeter and moister than yams. They have a lower concentration of starch, which makes them softer and more prone to breaking down when cooked.
To cook sweet potatoes, you can use a variety of methods, including baking, boiling, steaming, or roasting. They’re well-suited for dishes like mashed sweet potatoes, sweet potato casserole, and roasted sweet potato soup.
Baking Sweet Potatoes
