What are the basic ingredients of bread?

* Flour: This provides the structure and body of the bread.

* Water: This helps activate the gluten in the flour, which gives the bread its elasticity.

* Yeast: This is a single-celled fungus that feeds on the sugars in the flour and produces carbon dioxide gas, which creates the air pockets that make bread light and airy.

* Salt: This adds flavor and helps to control the yeast's activity.

These are the essential ingredients, but many breads also include:

* Fat: This can be butter, oil, or shortening, and it adds richness and tenderness.

* Sugar: This feeds the yeast and helps develop the flavor.

* Other ingredients: These can include milk, eggs, herbs, spices, seeds, and nuts, which add flavor and texture.

The specific proportions of each ingredient will vary depending on the type of bread being made. However, these basic ingredients form the foundation for all bread, from simple white loaves to complex sourdoughs.
