PREHEAT barbecue to medium-high heat. Mix together barbecue sauce, orange marmalade and hot pepper sauce until well blended.

CUT ribs into 2-rib sections. Place half of the ribs in single layer in centre of large sheet of heavy-duty foil. Bring up long sides of foil. Double fold short ends to seal, leaving top open. Place 3 or 4 ice cubes in packet through opening. Double fold top to seal, leaving room for heat circulation. Repeat with another sheet of foil and remaining ribs to make a second packet.

GRILL, covered, 45 min. to 1 hr. or until ribs are cooked through. Remove ribs from foil and return to barbecue; brush with barbecue sauce mixture. Grill an additional 10 to 15 min., turning occasionally and brushing with the remaining barbecue sauce mixture.
