Without trying to sound like a boob or a moron, what is the difference between these two cuts? I searched the forums and got some really good information, but the reason I ask this question.......AGAIN......is: Can these cuts of beef be used interchangeably? Is this a simple yes or no answer? I want to do a Prime Rib for Christmas or New Years eve. I went to Sam's Club and they have display cases LOADED with Rib Eye Roasts but no Standing Rib Roast. They do not stock Standing Rib Roasts anymore. What do I do?
