Not a Yam

Okay, let’s straighten this out once and for all. Those big orange roots you find in the grocery store are not yams. Got that? As a matter of fact, it’s a good bet that most of the people who read this blog have never even seen a yam unless they’ve traveled to an area with a significant West Indian or Asian population or to the tropics where yams are grown.

Yam is the common name for some plant species in the genus Dioscorea (family Dioscoreaceae) that form edible tubers. These are perennial herbaceous vines cultivated for the consumption of their starchy tubers in Africa, Asia, Latin America, the Caribbean and Oceania. The sweet potato (Ipomoea batatas) is a large, starchy, sweet-tasting, tuberous root native to tropical America related to morning glories.

The sweet potato is a staple of the American South and has been adopted by other cuisines around the world. The root is long and tapered, with a smooth skin of yellow, orange, red, brown, purple, or beige. Its flesh is rich and succulent.. The sweet potato is the state vegetable of North Carolina, and the Sweet Potato Capitol of the World is Vardaman, Mississippi. Sweet potatoes came to be called yams by West Indian and African natives and the name endured. To prevent confusion, the USDA requires sweet potatoes labeled as “yams” to also be labeled as “sweet potatoes”. If you see a can of yams in the store, you’ll find “sweet potatoes” in the ingredients.

So there.
