I have a suggestion to make your corn on the grill so that it is crunchy, yet moist, and the silk comes off super easy. SOAK your ears of corn for 30-45 minutes in water. Just dump them in a sink full of water or something similar. Put something heavy over them so that they are submerged in the water. Hold each upside down to drain before grilling. We grill our corn on the top rack for 30-40 minutes. When you remove the husks, the silk comes right off and leaves behind tender, yet crunchy corn. YUM!
