thermometer. Brush with the sauce for the last 30 minutes of cooking. To roast on the grill, place the meat over a drip pan with the hot coals surrounding the drip pan, or pushed back. Turn and baste the meat as needed to cook evenly. Grill 1 1/2 to 2 1/2 hours. Let the meat stand, on a platter, 20 to 30 minutes before carving. Heat the sauce and serve with the meat. NOTE: Any leftovers make great sandwiches and beef salads.
