One Cob of Sweet Corn per person (or more)
Butter
Salt and Pepper

Do Not Shuck the Corn on the Cob!  Peel the outside layers down and remove the silks.  Cut the pointy end off the corn if necessary.
Liberally spread butter on the ear of corn
Sprinkle with Salt and Pepper to taste
Fold the shucks back up over the ear of corn.
Wrap tightly with aluminum foil
Cover with hot coals on grill or campfire.  Let cook for 30 to 45 minutes.  (if you can't cover with coals, be sure to turn the cobs frequently to prevent parching on one side, cook slightly longer)
