Angel Food Cake Secret Weapon |
Angel food cake is based on an egg white foam created by thousands of bubbles. In order to make bubbles in a liquid there needs to be something to break the surface tension of the liquid. Take water for instance, it will not create stable bubbles on its own, this is because the water molecules are too attracted to each other. Add soap and the surface tension is reduced allowing bubbles to form. Bubbles are round because a sphere has the least surface area of any shape and thus is the easiest to form. Egg whites contain a good deal of protein and when broken up, by physical agitation, they allow bubbles to form. These bubbles gives angel food cake its lightness and its lift, as there are no chemical or biological leaveners (baking powder, baking soda, yeast) in the recipe.

One of the famous qualities of this cake is that it is fat free, no butter, no oil, no nothing and I can't say that the fat is greatly missed. Its even pretty low in calories, approximately 173 calories for 1/12 of the cake (that's according to http://caloriecount.about.com/cc/recipe_analysis.php, pretty cool site). The cake is pretty sweet and almost reminds me of a marshmallow in flavour. The cake on its own is pretty good but it really shines when paired with something else like jam. Toppings are great but they can quickly send the low-calorie and fat free status out the window.
A few notes on pans: this cake is supposed to be baked in a tube pan, this was not a problem. The problem occurred when the recipe said to turn the tube pan upside down to let it cool. This was supposed to stop the cake from falling and loosing its lightness. After about a minute upside down the cake fell right out of the pan therefore I am not sure if the upside down part is a good idea. Secondly, in order for the cake to "climb" the walls of the pan during cooking the pan should not be greased. As you can imagine the outside layer of the cake sticks to the pan, leaving a nice mess. I shouldn't complain too much, a soak in some hot water removed the stuck on cake without too much effort.
Final thoughts: when I go for dessert I want something really rich and dense, so angel food cake is not my favourite dessert in the world. It is a viable option for those with a sweet tooth looking to watch their waste lines, but beware of excess toppings!
