Wheat flour is a common ingredient made by grinding wheat grains into a fine powder. It is primarily used in baking and cooking, providing structure and texture to various foods like bread, cakes, and pastries. The type of wheat used can affect the flour's properties, with hard wheat being high in protein and ideal for bread-making, while soft wheat is better suited for cakes and cookies. There are different varieties of wheat flour, including all-purpose flour, whole wheat flour, and bread flour. Each type has unique characteristics that make it suitable for specific recipes. Whole wheat flour retains the bran and germ of the wheat, offering more nutrients and fiber compared to refined flours.
