Question: what is the difference between prime rib and rib eye roast?
Answer: The prime rib is a large roasting joint, often containing large sections of the rib bone. The ribeye, by comparison, is cut from the most tender part of the rib, between the 6th and 12th rib, and is a heavily marbled slice of the longissimus dorsi muscle. It's easier to understand once you see it with your own eyes.
