The pan is ready when the batter is poured and it sizzles. The pan should not be smoking. Stir the batter and pour in 1 or 2 divets for testers. Cover and let cook for 5 minutes and check. The cake should be brown around the outside, but not burnt. Carefully take out the cakes by scraping around them with a spoon. If the cakes stick too much, add a tablespoon of rice flour and try again.
