HEAT grill to medium heat. PLACE half the ribs in single layer on large sheet heavy-duty foil. Mix sugar and seasonings; rub half evenly onto both sides of ribs. Bring up foil sides. Double fold top and one end to seal packet. Add ¼ cup water to packet through open end. Double fold remaining end, leaving room for heat circulation inside. Repeat to make second packet. GRILL 45 min. to 1 hour or until ribs are done. Remove ribs from foil; discard foil. MIX remaining ingredients until blended. RETURN ribs to grill; brush with half the marmalade mixture. Grill 15 min., turning and brushing occasionally with remaining marmalade mixture.
