When I built a new fire pit at our campsite I sized it to fit a Weber replacement grill we got at Walmart. Anxious to try it out, I soaked some fresh corn in water for 30 minutes and placed it over some hot coals along with some oysters. I cooked the corn for 20 minutes turning it every so often. It came out just perfect! It seems to have more flavor and is juicier as well. Since then we have cooked it at home over the gas grill with the same results. Martha sez: It was better at the campsite because we didn't get corn silk and burnt husks all over the kitchen floor!
When you cook the corn with the husk on you also get an additional bonus; a built in handle. Late summer corn is soooooo good!
