Steps:

Preheat your oven to 450 degrees. * Use a paper towel to pat the roast dry. * Rub butter on the cut ends of the roast. * Create a seasoning rub or paste with ingredients such as pepper, coarse salt, garlic powder, and onion powder. Make a series of ½ inch deep slits all over the top of the roast as well as the sides. Rub your seasonings all over the roast, covering all exposed meat. * Place the roast in a heavy metal roasting pan, bone-side down. No matter what size roast you have, you will start it in a pre-heated 450 degree oven for 15 minutes then reduce the temperature to 325 degrees for the balance of cooking time. Cooking times will vary depending on size of the roast and desired level of doneness. The following chart gives approximate times for to reach "rare" at various sizes. Every half hour or so, baste the ends of the roast with the drippings. Use your meat thermometer about a half hour before the expected end of the roasting time. Make sure to insert it in the thickest part of the meat, not touching the fat or bone. When the internal temperature reaches 120°, pull it out of the oven and cover with foil. Let the roast sit for twenty to thirty minutes. It will continue to cook during this time, reaching a temperature of about 125° to 130°. This resting period allows the juices and flavors to permeate the roast. Rare meats measure in at 120° to 125° with a bright red center that grows slightly pinkish towards the exterior. Medium rare meats measure between 130° to 135° and are characterized by their extremely pink center portion that grows brown towards the exterior. Medium meats have a light pink center, brown outer portions and readings of about 140° to 145°. Medium well is not pink at all and is achieved at 150° to 155°. Well done is reached at 160° and above and is characterized by a uniform brown color.
