What is the key difference between prime rib and ribeye?

The key difference highlighted in the correct choice lies in the cooking methods and presentation of prime rib compared to ribeye steaks. Prime rib is indeed typically slow roasted, which allows for even cooking and helps preserve the moisture and richness of the meat. It is often cooked as an entire prime rib roast and then sliced into portions, making it a staple in traditional dining settings, especially during special occasions or holiday meals.

On the other hand, ribeye steaks, which are cut from the same rib area but represent individual portions, are often seared or grilled. This method of cooking provides a flavorful crust while keeping the inside juicy, and each ribeye can be cooked to the patron's preferred level of doneness. Therefore, while both cuts come from the rib section of the cow, the prime rib is presented in a way that emphasizes slow roasting and serving it in pre-cut portions, while the ribeye offers more flexibility in cooking style and doneness.

The other options do not accurately describe the distinct preparations and serving styles of these cuts, hence they do not reflect the key difference between prime rib and ribeye as effectively as the chosen answer.
