Step 1

MIX the sugar, paprika, chili powder, salt, and garlic powder in a medium bowl. Rub all surfaces of meat generously with the dry mixture. Place ribs in the prepared dish in a single layer. Cover and chill the ribs in the refrigerator 30 minutes to 1 hour.

Step 2

PREHEAT grill to medium indirect heat. Center one-fourth of the ribs and two ice cubes on a sheet (12x18 inches) of Reynolds Wrap ® Heavy Duty Aluminum Foil. Bring up foil sides. Double-fold top and ends to seal packet, leaving room for heat circulation inside. Repeat to make four packets.

Step 3

GRILL packets on a grill rack over medium (375°F to 400°F) indirect heat in covered grill 1 1/2 to 2 hours or until tender.

Step 4

OPEN packets carefully by cutting along top folds with a sharp knife, allowing steam to escape; then open top of foil packet. Brush ribs with 1/2 cup barbecue sauce. Continue grilling over direct medium heat, covered, 5 minutes more until browned and crisp, turning once.

Step 5

SERVE with additional barbecue sauce as desired.
