Take your room temperature rib roast and make sure all excess fat is trimmed off. Leave a thin layer of fat all around that can stay on the meat, as this helps it to cook properly. Spread approximately 2 tablespoons of butter on the ends of the prime rib and place it fat side up in a non-stick metal pan. Allow the prime rib to cook at 450 degrees for about 15 minutes, and then turn the oven down to 325 for the remainder of the time. Every half hour or so, take the fat that has dropped into the roasting pan and smear it on the ends of the roast with a basting brush.
