Allow me to say that I never met a cob of grilled corn I didn't like, no matter how it was prepared. However, the best corn I ever ate has it's roots in the dim dawn of "roasting ears".
The old Sportsmans club used to have a yearly "bring your own" steak fry that was timed with the first sweet corn picking.
A couple of old timers were in charge of roasting the corn, and this was done by soaking the cobs as they came from the field, in wash tubs of water. They piled up large amounts of wood in three places, then burned it down to coals. Most of the coals were then raked to one side, then the corn was drained and dumped on the few remaining coals and hot ground. The coals were then raked back over the corn for 12 to 15 minutes, then retreaved with rakes.
The outside husks were always fairly charred, while the water in the inside husks and silk protected and steamed the corn to pefection. The singed husks and coals imparted a great flavor. The big trick was to get the cob peeled without burning your fingers.
Alas, the club no longer exists, but our family still does a few dozen ears every year in this manner. Great Stuff !!!!
