Definition of Prime Ribにまつわる役立つ知識を詳しく紐解きます。

Technically, prime rib comes from the primal rib section of the cow—specifically ribs six through twelve. That’s the same spot as a ribeye steak, just bigger and cooked as a whole roast. The name “prime” doesn’t mean it’s the highest grade (though it can be). It refers to the primal part of the animal. Confusing? Yes. Delicious? Absolutely.

Here’s the funny part: most prime rib you eat isn’t actually “Prime” grade. Only about 2-3% of beef gets that top USDA Prime stamp. The rest is “Choice” or “Select.” But we still call it prime rib because tradition is a stubborn, tasty thing. So when someone brags about “prime rib,” they’re really bragging about the location on the cow, not necessarily the quality. Sneaky, huh?
