Prime rib, regardless of size

Salt and pepper meat. Place in uncovered pan at 375 degrees for 1 hour. Secret to a delicious roast is DO NOT OPEN OVEN DOOR! Leave roast in oven and 1 hour before serving, set oven temperature to 300 degrees. Bake 55 minutes for well done, 50 minutes medium, 45 minutes rare. (Oven must be in excellent working condition. Roast is superb!)
