The primary ingredient in a soufflé is eggs. This classic French dish can be either sweet or savory and is characterized by its fluffy texture and rise achieved through beaten egg whites. The base of a soufflé is usually made from a flavorful mixture of egg yolks combined with other ingredients like cheese or chocolate, depending on the type being prepared. Once the egg whites are whipped into stiff peaks and folded gently into the base, the soufflé is baked until it puffs up and develops a delicate, airy structure.
