Core a large cooking apple (the firmer and tarter the better). Fill the whole with red cinnamon candies, raisins and a bit of butter. Dot the rest of the apple with butter.
Place the apple in the center of a sheet of foil. Bring the corners together and twist, leaving the foil rather loose around the apple.
Cook on your Hasty-Bake at about 200°F with the heat deflector in place over the coals until the apple is soft, about 30 minutes.
