Roasting the Corn. Place the corn at the base of the fire covered in coals and ash using a pair of tongs. Ideally you want to cover the foil-wrapped corn husks completely to in that bed of embers to prevent scorching. Each ear takes about 20 minutes to roast. After removing the ears from the campfire with a pair of tongs, allow them to cool for 5 to 10 minutes, until you can easily unwrap the foil and serve.
