Run water over cobs to take off the last of the chaff. In a roaster cover the cobs with water and boil gently for 30 minutes. A large quantity of water must be used as the corncobs absorb a great deal.
Strain 3 cups of the red corn likker into a pan; add one package of Sure jell. Let this come to a hard boil, then add sugar. When this comes to a fast boil, let it boil hard for one minute or until it starts to jell when you lift out the spoon. Set aside and skim.
