Meanwhile, place a rack in the bottom third of the oven and heat to 200F. Place the roast fat side up (so that it's resting on the bones) on a rack set in a roasting pan. Place in the preheated oven and roast until a thermometer reads 118F, about 5 to 6 hours (about 30 minutes per pound). When the internal temperature of the roast is at 118F, remove the pan from the oven onto a wire rack and cover it loosely with foil. Keep in a warm place for at least 30 minutes or up to one hour.
