To prepare the coating, in a separate medium bowl, combine cornmeal, flour, egg white, milk, salt, and pepper. Heat up a large, deep skillet and fill it with 1-2 inches of oil. Take the frozen corn mixture from the sheet and dip each piece into the batter mixture. Fry the battered corn in the hot oil until they are golden brown. Once done, remove from the oil and place on paper towels to drain any excess.
