Rewrap the husks around the corn. Place corn on grate of grill over low heat. Grill 15 to 20 min. or until tender, turning frequently to prevent the husks from burning. Remove the corn from the grill. Using a towel or oven mitt to protect your hands, peel back the husks and cut off the kernels. How to remove the kernels from the cooked ears of corn: Cut off the tips of the ears to flatten the ends. Stand the cobs upright on the flat ends. Using a very sharp knife, cut downward, removing 3 or 4 rows of kernels at a time.
