Stuff turkey. Rub outside with bacon fat, butter and salt. Place in extra large brown paper bag. Seal opening securely with a wire tie. Place in roasting pan in cold oven. Set oven for 500 degrees for the first hour; 400 degrees for the second hour; and 300 degrees for the third hour.
Chef's Note: With this method, the turkey is always done to perfection whether it's 12 pounds or 24 pounds.
