First find a pot large enough to hold all of the corn you will be cooking and let it begin heating up. Meanwhile take your corn on the cob and shuck it. Blasting water from the faucet onto it can be helpful in removing stubborn silk. Once the water is boiling. Throw in the corn and cover. The amount of time to let your corn boil ranges from 1-10 minutes depending on how soft you want your corn. I like it soft, so I do it for 10 minutes. Remove from the water with tongs. Dress as you see fit with salt, pepper and butter.
Cut off excess silk hanging from the end and remove loose husk. Completely submerse all of the corn you will be cooking under water. This will provide extra moisture for cooking. Let the ears of corn soak for at least 15 minutes prior to cooking. While your corn is soaking, go ahead and prepare the grill. Remove the corn from the water and pour out any excess. Place the corn on the grill and cover. Turn the corn every 5 minutes. The ears will turn brown and might even catch on fire - this is fine, let them cook. Just be sure to turn them often. The water that you soaked them in is steaming them inside the husks. Remove the corn from the grill with tongs. Grasping one end, peel the silk and leaves from the top down (like a banana). They should all come off in one piece. Ashes will get on the corn, this is ok. Dress as you see fit with salt, pepper and butter.
