Understanding Egg Whites and Their Culinary Uses
What Are Egg Whites?
Egg whites, also known as albumen, are the clear, viscous liquid that surrounds the yolk inside an egg. They are composed primarily of water (about 90%) and proteins, with a small amount of minerals and trace elements. When beaten, egg whites can trap air, creating a foam that is essential in many baked goods.
Key Properties of Egg Whites
- High protein content: Mainly ovalbumin, which helps in forming stable foams.
- Low fat and sugar: Making them ideal for light, airy textures.
- Ability to be whipped: When whipped properly, they increase in volume and become stiff, forming peaks that hold their shape.
Common Culinary Uses of Egg Whites
- Meringues
- Macarons
- Soufflés
- Pavlovas
- Angel food cake
- Folding into batters for lightness
- Clarifying broths and consommés

The Classic Pairing: Egg Whites and Chocolate
The Chemistry Behind the Pairing
Combining egg whites and chocolate allows bakers and chefs to create desserts that are both airy and rich. Egg whites provide structure and volume, while chocolate adds flavor and decadence. When whipped egg whites are folded into chocolate mixtures, they impart a lightness that elevates the dish from dense to delicate.
The key to a successful pairing lies in balancing the textures and flavors. For instance, incorporating whipped egg whites into a chocolate mousse results in a silky, cloud-like texture that melts in your mouth.
