1 Prepare your grill, gas or charcoal, with direct, high heat, about 550°F.
2 Place the corn in their husks on the hot grill. Cover. Turn the corn occasionally, until the husks are charred on all sides, about 15 to 20 minutes.
3 Remove corn from grill. Let sit for 5 minutes. Use a hand towel to protect your hands while removing the silks and charred husks from the corn.
Serve hot, with butter.
