To grill the corn, carefully pull back the husks from the tops of the ears to remove the silk, being careful not to detach the husks from the bottoms of the ears. Rinse corn. Rewrap husks around corn. Place corn on grate of barbecue over low heat. Grill 15 to 20 min. or until tender, turning frequently to prevent the husks from burning. Remove corn from barbecue. Using a towel or oven mitt to protect your hands, peel back the husks and cut off the kernels.
