Have you ever thought about the function of an egg? I mean think about it. Why do we add eggs to nearly everything in the bakeshop? Because, eggs are used as emulsifiers in your batter. What do I mean by that?
Most of you know that oil and water do not mix. This is true no matter what the shape or form these two substances take. In salad dressings this is called a "temporary emulsion" where you take two things that don't mix and beat them into submission with a whisk. However, no matter how fiercely you beat them, oil and water will never mix unless there is an emulsifier or binder. How does this apply to the bakeshop? Think of the basic creaming method for making a cake. You start with butter and sugar. The butter is your fat, and the eggs you will add later contain water. The sugar and flour act as your emulsifier or as the binder that takes a "temporary emulsion" and makes it a "permanent emulsion". Which is why some recipes tell you to alternate your wet and dry ingredients. because, if you add both wet and dry ingredients at once your emulsion will break and cause your cake to "curdle". In the words of Alton Brown "This is not good eats". :)
Why all the talk of emulsions? Because it's important. Now, let's talk about eggs.
Eggs consist of the following 4 parts:
Shell
Yolk
White
Chalaze
The chalaze is the filmy white chord like thing that comes out of the shell when you crack an egg. The longer the chalaze the fresher the egg.
In the bakeshop eggs:
Add structure to cakes
Makes the batter smooth
Yolks serve as fat and eggs
Add moisture (because eggs are made up of 75% water)
And these are just its function in cakes. So it's true, every ingredient serves a purpose and has its own job. Kind of like the body of Christ, we need each other in order to function well. Otherwise we are made up of all Hands, or all eyes. Or, to apply it to cakes, we can't all be flour, or baking powder, vanilla, or eggs. We each have to be a separate ingredient or the cake won't turn out or taste good.
Speaking of cakes...we start decorating cakes in Cake Decorating class Monday so I will try and post pictures then. So, dear readers, what is your favorite cake?
Well, I hope this lesson on emulsions and eggs has helped you to understand, a little better, what goes on in the baking of a cake. In the words of Julia Child, "Bon Apetite".
