3.3 Eggs and Their Functions - Eggs and Their Functions

1. Binding Agent

Eggs act as a binding agent in baked goods, helping to hold the ingredients together. When eggs are mixed into batters or doughs, they form a network that traps air and moisture, creating a cohesive structure. This is particularly important in recipes like cakes, cookies, and muffins, where the final product needs to hold its shape.

Imagine eggs as the glue that holds a puzzle together. Just as glue ensures that the pieces of a puzzle stay in place, eggs ensure that the ingredients in your baked goods do not separate during the baking process. For example, in a cake batter, eggs help to bind the flour, sugar, and butter, resulting in a uniform texture.

2. Leavening Agent

Eggs contribute to leavening in baked goods by trapping air bubbles during the mixing process. When eggs are beaten, they incorporate air, which expands when heated, causing the baked good to rise. This is especially noticeable in recipes like soufflés and meringues, where the egg whites are whipped to a stiff peak before baking.

Think of eggs as tiny balloons that fill with air. Just as balloons expand when filled with air, eggs expand when heated, causing baked goods to rise. For instance, in a soufflé, the whipped egg whites trap air, which expands as the soufflé bakes, resulting in a light and airy texture.

3. Moisture and Flavor

Eggs add moisture and richness to baked goods, enhancing their overall flavor and texture. The fat and protein in eggs contribute to a tender crumb and a moist interior. This is particularly important in recipes like custards, bread, and pastries, where moisture and flavor are key components.

Consider eggs as the secret ingredient that adds both moisture and flavor to your baked goods. Just as a chef adds seasoning to enhance the taste of a dish, eggs add moisture and richness to baked goods, making them more enjoyable to eat. For example, in a brioche bread, the eggs contribute to its soft, buttery texture and rich flavor.
