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 1.5 to 2.5 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.
