These are a bit tricky to bake just right. Once they puff up, press down on the center. If they indent easily, they are not done; if they retain their shape, they are finished. The bottoms begin to blacken once they are finished so it is important to remove them once they have achieved this stage.
Remove immediately from baking sheet and place on cooling rack.
Makes about 2 dozen. Easily doubled.
