It's marked Beef Rib Ribeye Roast? I asked for prime rib and that's what the commissary cut for me with two or three ribs tied. It's like ten pounds of meat. I screwed it up so bad last year - it was tough in some places and raw in others. The cat who eats out of the dump liked it - that should tell you something.Prime Rib? Bone in or no?
Any suggestions - you sound like you know what you're doing.
