To create the perfect soufflé, it helps to understand the science behind it.
Egg whites are made entirely of protein, while egg yolks contain a mixture of both protein and fat. When you beat egg whites, you are mixing air into the mixture, and the protein from the egg whites forms a skin around the air bubbles. As the soufflé bakes, the heat causes the air captured in the egg whites to expand, creating the puff. When the soufflé comes out of the oven and begins to cool, the air contracts and the soufflé begins to deflate.
Simply put, the rise and fall of your soufflé comes down to the egg whites.
