HEAT barbecue to medium heat. Mix seasonings; rub onto both sides of ribs. Place half the ribs in single layer in centre of large sheet of heavy-duty foil. Bring up sides of foil; double fold top and one end. Add 1/4 cup apple juice through open end of packet. Double fold remaining end to seal packet, leaving room for heat to circulate inside. Repeat to make second packet.

PLACE packets on grate of barbecue; cover with lid. Grill 45 min. to 1 hour or until ribs are done. Remove ribs from foil; discard foil.

RETURN ribs to barbecue; brush with 1/2 cup barbecue sauce. Grill 15 min., turning occasionally and brushing with remaining sauce.
