The primary ingredient used in bread is "flour." Typically sourced from wheat, flour forms the foundational component of bread and provides structure, texture, and essential carbohydrates. During the bread-making process, flour is combined with water, yeast, and salt to create the dough. The gluten proteins in wheat flour develop a network that allows the dough to rise and maintain its shape during baking. Variations in flour types, such as whole wheat, all-purpose, or bread flour, influence the flavor and texture of the final product, making bread a versatile and essential food staple worldwide.
