The first step to grill a corn on the cob is to purchase fresh corn on the cob from your local super market or grocery store. Consider slightly peeling back the husk and silk at the time of picking your corn to ensure you are getting a good piece.
It is advised to remove all the silk of the corn while keeping the husk intact. Take your time to remove as much corn silk as possible. Another advantage of grilling the corn is that the excess silk will also burn when the corn is placed on the grill.
Next, dip the corn in a container of warm water for about 15 to 20 minutes. Wet corn can be cooked on the grill for a long time without it getting burned and therefore it is important to make sure that your corn is soaked in water before cooked on the grilled.
Remove any excess water by shaking off your corn. Although you want the corn to be wet, it is should not be completely drenched. Heat up your coal grill or electric grill and place the corn on it. Set the temperature of the grill to about 135 degree Centigrade. Make sure the coals on charcoal grill are not flaming to avoid burning your corn.
Turn the corn upside down every 5 to 10 minutes depending on the temperature of the grill. Continue to grill the corn until the husk is black and charred.
Remove your corn from the grill. Separate the husk and add some salt and butter to it for enhanced taste.
