When it comes to prime rib and there are two basic camps. One side says you must cook it with the bones attached. The idea is that the bones give more flavor to the meat. The other side says that the meat can be just as flavorful without the bones, and easier to carve. If you want to give it a try, here is a boneless prime roast recipe. There are plenty of variations on the basic boneless prime roast recipe so feel free to improvise. The reason this boneless prime rib recipe uses rock salt is to seal the exterior of the meat so that it remains tasty and juicy. The beef will not taste salty.
