What's the Difference Between a Yam and a Sweet Potatoにまつわる最新トピックを詳しく紐解きます。

So, why does your supermarket have a bin labeled "Yams" filled with sweet potatoes? It’s a marketing trick from the 1930s. Farmers in the South grew a particularly moist, orange sweet potato variety and needed a way to separate it from the dry, pale ones. They borrowed the word "yam" because it sounded exotic and different.

8 Ways To Tell The Difference Between Sweet Potatoes And Yams – YLRDTO

The USDA now requires anything labeled "yam" in a store to also say "sweet potato" on it, just to cover their legal butts. So next time you see a "yam," flip the tag. It will likely say ‘Sweet Potato’ in tiny letters. It’s like finding out your friend’s "fancy" name is actually just a nickname they made up in college.

How to Tell Them Apart (Without a DNA Test)

Here’s your cheat sheet. Sweet potatoes: smooth, thin skin, orange or purple flesh, pointy ends, tastes like a dessert. True yams: thick, rough, scaly skin (like tree bark), white or purple flesh (rarely orange), huge in size, and tastes like a potato’s grumpy uncle.

If you ever see a root vegetable that’s the size of your toddler’s leg and covered in what looks like tree bark, you’ve found a real yam. Otherwise, you’re probably holding a sweet potato. And honestly, that’s fine—they’re the better choice for 90% of recipes anyway.

The ultimate test? Try eating it raw. A sweet potato is crunchy and slightly sweet. A raw yam? You’ll feel like you bit into a piece of wood. I did this once for a "research" snack. I don’t recommend it.
