The primary ingredient in standard bread is flour. Typically made from wheat, flour serves as the base for the dough. When combined with water and yeast, it forms a pliable mixture that can be baked into bread. The type of flour used, such as all-purpose, whole wheat, or bread flour, influences the texture and flavor of the final product. Other common ingredients may include salt, sugar, and fats, but flour remains essential, providing the structure and bulk of the bread. Bread has been a staple food in many cultures for centuries, symbolizing sustenance and nourishment.
