Heat oven to 325°F. Sprinkle pork with salt and pepper. On rack in shallow roasting pan, place pork with bone ends up. Wrap bone ends in foil to prevent excessive browning. Insert ovenproof meat thermometer so tip is in thickest part of pork and does not touch bone or rest in fat. Place small heatproof bowl or crumpled foil in crown to hold shape of roast evenly. Do not add water.
