What is the function of egg in chocolate chip cookies?

Eggs play a crucial role in chocolate chip cookies, contributing to their texture, flavor, and overall structure. Here's a breakdown of their functions:

1. Binding:

- Eggs act as a binder, holding the dry ingredients (flour, sugar, etc.) together with the wet ingredients (butter, milk, etc.). This creates a cohesive dough that can be scooped and baked.

2. Structure and Texture:

- The proteins in eggs coagulate during baking, forming a network that gives the cookies their structure and chewiness.

- Egg yolks also contribute to the richness and tenderness of the cookies.

3. Flavor:

- Eggs provide a subtle richness and depth of flavor to the cookies.

4. Color:

- The yolks contribute to the golden-brown color of the cookies.

5. Spread Control:

- Eggs help to control the spread of the cookies during baking, preventing them from becoming thin and flat.

In Summary: Eggs are essential for creating the perfect chocolate chip cookie. They provide structure, flavor, color, and help control spread, resulting in a delicious and satisfying treat.
