"Sweet summer corn, a whole-grain source of potassium, is delicious on it's own. Even better:spread with one of the following butter blends created by Bonaparte for a luxuriously indulgent touch." Self Magazine, August 2007 edition. Chill flavored butters for at least 2-3 hours. It would probably be easier to prepare the butter the day before, that way all you have to do is grill the corn!
