How to Make It
Light a grill. In a bowl, mix the butter with the Parmesan and garlic. Season with salt and pepper.
Strip the husks from each ear of corn and remove the silks. Using kitchen string, tie the husks together at the end of each ear to form a handle.
Lightly brush the grate with oil. Grill the corn over a medium-hot fire, turning, until partially cooked, about 5 minutes. Brush the corn with the Parmesan butter and continue grilling, turning frequently and brushing with more butter, until deeply browned and tender, about 5 minutes longer. Serve at once with the remaining Parmesan butter.
