Difference Between a Yam and a Sweet Potatoの主要なニュースを丁寧にまとめました。全体像を一目で把握できます。

Here’s the kicker: Most “yams” in America are actually sweet potatoes. Yep, it’s a marketing plot twist. In the 1930s, Louisiana farmers wanted to distinguish their orange-fleshed sweet potatoes from the pale ones. They called them “yams” because it sounded exotic. It stuck. Now, you’re buying a sweet potato in a yam’s costume.

Real yams are a whole different beast. They are starchy, dry, and taste like a potato’s earthy cousin. Sweet potatoes are sugary, moist, and practically dessert. One is for roasting. The other is for, well, confusing everyone.

Look at Their Skin

The easiest way to tell them apart? Check the skin. Sweet potatoes have thin, smooth skin that’s reddish-brown or pale beige. Real yams look like tree bark. They are rough, scaly, and sometimes hairy. If it looks like it wrestled a dinosaur, it’s a yam.

Cut one open, and the colors shout the truth. Sweet potatoes are bright orange, purple, or yellow inside. Yams are pale yellow, white, or even purple—but they’re never that vibrant Halloween orange. That orange glow is a sweet potato’s calling card.
