Prime Rib with Yorkshire Pudding and Onion Mushroom Gravy

1 (3 ½ to 4 pound) standing rib roast
Salt
Freshly ground pepper

About 4 hours before cooking, remove roast from refrigerator to allow to come to room temperature.

Line the bottom of a baking dish with rack with aluminum foil. Insert rack; top with aluminum foil and pierce all over with the tines of a fork (this will allow the fats to fall into the pan during cooking without spattering).

Preheat oven to 500º F.

Generously sprinkle all sides of roast with salt and pepper. Place fat side up on prepared rack. Cook roast at 500º F for 20 minutes. Lower heat to 325º F and continue cooking for a total cooking time (including the 20 minutes at 500º) of 40 minutes per pound. Remove from oven and let sit 30 minutes before serving. Meanwhile, prepare the Yorkshire Pudding. Serve with little potatoes cooked with onions, steamed brussel sprouts, onion-mushroom gravy (recipe below), and a red wine. Yield: 4 servings.
