Instructions: Prepare a medium-hot fire for indirect heat cooking in a covered grill according to manufacturers instructions. Position rack 4 to 6 inches from fire. Soak 3 handfuls of hickory chips in water to cover for at least 20 minutes.

Meanwhile, in a saucepan over medium heat, warm oil, add onion and garlic and saute until tender, about 5 minutes. Stir in tomato sauce, ketchup, vinegar, orange juice, brown sugar, mustard, Worchestshire, salt and pepper. Bring to a boil, reduce heat to low, and cook until thick, about 15 minutes.

Sprinkle soaked hickory chips over hot coals. Unwrap ribs, return to grill rack, and cover grill, partially closing the vents. Grill turning occasionally, until tender, 20 to 25 minutes. During last 10 minutes of grilling, brush ribs with sauce.
