What is the main ingredient in waffles?

While batter itself is a mixture, the key components of waffle batter are:

* Flour: Provides structure and texture.

* Eggs: Adds richness, binds ingredients, and helps create a fluffy texture.

* Milk: Provides moisture and helps the batter to rise.

* Butter: Adds flavor and richness.

* Sugar: Adds sweetness.

There can be other ingredients added depending on the recipe, like baking powder, baking soda, vanilla extract, or spices.
