Step 1

Mix paprika and mustard until blended; rub evenly onto both sides of ribs. Refrigerate 1 hour. Meanwhile, soak wood chips in water.

Step 2

Drain wood chips. If using gas grill, place half the chips on each of 2 large sheets of heavy-duty foil; fold each to make packet. Use fork to poke several holes in top of each packet.

Step 3

Heat grill for indirect grilling: Light one side of grill, leaving other side unlit. Close lid; heat grill to 300ºF. Place 1 foil packet over lit burners in bottom of grill. (Or if using charcoal grill, sprinkle half the drained chips directly over hot coals.)

Step 4

Place ribs, meat sides up, on grate over unlit area. Grill 2 hours, monitoring for consistent grill temperature and adding remaining wood chips halfway through the grilling time.

Step 5

Brush ribs with half the barbecue sauce. Grill 30 min., turning and brushing occasionally with remaining barbecue sauce.
