What’s the difference between sweet potatoes and yams?

The primary difference between sweet potatoes and yams lies in their appearance:
Sweet Potatoes:
As mentioned earlier, sweet potatoes come in two main varieties. The soft variety, often labeled as “yams,” have dark orange flesh and are sweet and moist when cooked. The firm variety, often labeled as “sweet potatoes,” have a lighter flesh that is less sweet and more starchy in texture.
Yams:
True yams are much larger than sweet potatoes and have rough, scaly skin that looks like tree bark. The flesh of yams can vary in color from white to purple or reddish-brown.
Flavor and Texture:
The taste and texture of sweet potatoes and yams also differ:
Sweet Potatoes:
Depending on the variety, sweet potatoes can have a sweet and creamy or firmer, starchier texture. They tend to have a milder, sweeter flavor, which makes them great for both savory and sweet dishes.
Yams:
Yams have a starchy, potato-like texture and a less sweet flavor compared to sweet potatoes. They are often described as being drier and less creamy.
Culinary Uses:
Knowing the differences between sweet potatoes and yams can help you choose the right one for your recipes:
Sweet Potatoes:
Soft sweet potatoes are perfect for making classic dishes like sweet potato pie, mashed sweet potatoes, or roasted sweet potato fries. They can also be used in soups, stews, and casseroles to add natural sweetness and creaminess. The firm variety is great for making sweet potato fries, chips, or gratins.
Yams:
Yams are commonly used in African, Caribbean, and Asian cuisines. They are often boiled, roasted, or fried and served as a side dish. Yams are also used in stews and soups, where their starchy texture can help thicken the broth.
