Peel back the husks of the corn without detaching them from the bottom of the cob. Remove silk and fold husks back into place to cover the corn.
Place corn in a sink or large bowl of water to soak for at least 15 minutes (it can soak overnight if needed).
Preheat grill to medium-high heat.
Remove corn from the water and shake off excess so it's not dripping. Place cobs on the grill and cook 15-20 minutes, turning occasionally.
Once corn is cooked to your liking remove from the grill, peel off husks and serve with butter, salt & pepper.
