The main ingredient in most bread is flour, typically made from wheat. Flour provides the necessary gluten proteins when mixed with water and kneaded, which gives bread its structure and texture. The type of flour can vary, including all-purpose, whole wheat, and bread flour, each contributing different flavors and textures to the bread. In addition to flour, other essential ingredients in bread making include water, yeast (which helps with leavening), and salt (which enhances flavor). The combination of these elements is what creates the beloved staple food that is bread, enjoyed in various forms worldwide.
