Back in the 1930s, Louisiana farmers started growing a soft, orange-fleshed sweet potato. They needed a way to market it as something special, so they borrowed the word “yam” from African and Caribbean traditions. The name stuck, but the vegetable didn’t change.
Today, if you buy a “yam” in a typical U.S. supermarket, you’re almost always getting a moist, orange sweet potato. The true yam is a completely different plant, native to Africa and Asia.
So, What’s a Real Yam?
A true yam is rough, scaly, and looks a bit like tree bark in vegetable form. Its flesh can be white, purple, or yellow, and it’s starchy and dry, not sweet like its American cousin.
If you’ve ever eaten pounded yam (a fluffy, dough-like side dish) at a West African restaurant, you’ve met the real deal. It’s savory, not sugary, and it can grow up to 100 pounds. Good luck fitting that in your oven.
