What are the ingredient of bread?

* Flour: Provides structure and texture to the bread. Wheat flour is most commonly used, but other flours like rye, barley, or spelt can also be used.

* Water: Activates the gluten in the flour, helping to form the dough's structure.

* Yeast: A living organism that ferments the sugar in the flour, producing carbon dioxide and alcohol, which create air pockets in the bread, giving it its rise and light texture.

* Salt: Enhances the flavor of the bread and controls the yeast's activity.

Additional Ingredients:

* Sugar: Provides food for the yeast and enhances flavor.

* Fat: Contributes to flavor, tenderness, and moisture. Examples include butter, oil, or shortening.

* Eggs: Add richness, color, and structure to the bread.

* Milk: Contributes to flavor, moisture, and browning.

* Additives: These can include flavorings, sweeteners, nuts, seeds, fruits, and other ingredients to customize the bread's flavor and texture.

The specific ingredients and proportions used in a bread recipe will vary depending on the type of bread being made. For example, a white sandwich loaf will typically use only flour, water, yeast, and salt, while a richer bread like challah will include eggs and sugar.
