In baking, egg whites are often used differently than egg yolks due to their unique properties. Egg whites are high in protein and contain very little fat, which makes them ideal for providing structure, volume, and stability to baked goods.

When whipped, egg whites trap air bubbles, and the proteins in them create a stable network that helps the mixture to hold its shape. These whipped egg whites, when folded into a cake batter, create a light and airy texture. This method is commonly used in recipes like sponge cakes or angel food cakes, where the goal is to achieve a light and fluffy texture.

On the other hand, egg yolks are rich in fat and act as emulsifiers. When egg yolks are cooked, they thicken and contribute to the richness and creamy texture of the final product. This is why pastry cream, custards, and other creamy fillings require the cooking of egg yolks. The heat causes the proteins in the yolks to coagulate and thicken the mixture.

Regarding "stuffing peaks" in baking, it's not entirely clear what you are referring to. If you meant "stiff peaks," this refers to the stage in whisking egg whites, where the beaten whites hold their shape and form peaks that stand up straight when the whisk is lifted. This is an important stage because it signifies that the egg whites are sufficiently whipped and can provide the desired structure and stability to the baked goods.

In terms of cooking eggs in a liquid, it depends on the specific recipe or technique being used. Cooking eggs in a liquid, such as poaching or boiling, allows the egg to cook gently and evenly. Poached or boiled eggs are often used in dishes like eggs Benedict or served on their own. Each method offers a different texture and taste to the final dish.

It's important to note that baking and cooking techniques can vary depending on the recipe and desired outcome. Chefs and bakers choose different methods based on the specific requirements of the dish they are preparing.
