The recipe above, provided by Alton Brown, host of "Good Eats", is very similar to the one that we used in class. It shows how it fits into the foam cake category by the key steps involved and also the final product.

The video above shows how angel food cake, the most well known foam cake, is made. Joy of Baking, who we have previously watched in class, does a very good job in providing us with an informational video on how angel food cakes are made.
Foam cakes are very similar to chiffon and sponge cakes in their overall structure and shape, but not in ingredients. Chiffon cakes utilize large amounts of oil and sponge cakes contain egg yolks. Like foam cakes, sponge cakes are risen mechanically by air beaten into the egg whites. Finally foam, chiffon, and sponge cakes are cooled inverted to prevent deflation.
