Prime rib roast is a luxurious dish to prepare, not only because it's exquisite but also because it's expensive. This is why you have to be sure to cook it to perfection. Some people like to cook it without salt and pepper. I've made it both ways, and I personally like it seasoned. In my opinion, there are two secrets to making sure your meat is juicy and well cooked. First, the meat should be at room temperature so that it cooks evenly. Second, you should let it rest 20-30 minutes after cooking to allow the juices to soak back into the meat. Enjoy!
