The corn husks will protect the corn from burning or drying out while it is on the hot grill. If you want a bit of char on your corn, peel off a few of the outer layers of the corn husks first, before grilling.
Place the corn in their husks on the hot grill. Cover the grill. Turn the corn occasionally, until the husks are completely blackened and charred on all sides, about 15 to 20 minutes.
Remove the corn from the grill. Let them sit for 5 minutes or until cool enough to handle. Remove the silks and charred husks from the corn.
Serve with butter, or you can sprinkle with a little chili powder, cotija cheese, and some lime juice for a Mexican twist.
