Remove the roast from the refrigerator at least 3 hours before it is to be cooked.
Preheat the oven to 325 degrees.
Rub the roast all over with salt and pepper. Be fairly generous in using both salt and pepper.
It is not necessary to use a roasting rack. Place the beef, rib-side down and fat-side up, in the center of the pan. Place the beef in the oven and leave it there, without basting, until it is done. Use the following table to determine the correct roasting time.
