Score roast in a diamond pattern, making cuts about 1/4-inch deep in fat. Sprinkle roast with salt and pepper.
Place roast, fat side up, on a rack in a shallow roasting pan. Insert meat thermometer in roast, if desired.
Bake roast, uncovered, at 450° for 15 minutes; reduce heat to 300°, and continue baking until desired degree of doneness: about 2 1/2 hours or 140° (rare); about 3 1/2 hours or 160° (medium).
Transfer roast to a warm platter, reserving 1/4 cup clear pan drippings for Individual Yorkshire Puddings. Let roast stand 20 minutes before slicing. Serve with Individual Yorkshire Puddings.
