Flour is a fine powder produced by grinding cereal grains, most commonly wheat, though it can also be made from rice, corn, barley, rye, or other grains. Wheat flour is the most widely used form in baking and cooking across the world. The flour's characteristics—including protein content, starch composition, and granule size—vary significantly depending on the type of wheat used, the milling process, and the portion of the grain retained. Common varieties include all-purpose flour (moderate protein content, suitable for general baking), bread flour (high protein content for strong gluten development), cake flour (low protein content for tender crumbs), and whole wheat flour (containing the bran and germ for increased fiber and nutrition).

The milling process involves cleaning the grain, conditioning it with moisture, grinding between rotating stones or metal rollers, and sifting to achieve the desired fineness. Wheat flour typically contains 10-14% water and various grades of fineness; all-purpose flour is the most versatile and widely available.

Flour is the foundation of countless baked goods, including breads, cakes, pastries, cookies, and pasta. It serves as a thickening agent in sauces and gravies through roux-making, and is essential for creating batters and doughs. In bread baking, flour's gluten proteins (glutenin and gliadin) hydrate and develop network structures that provide elasticity and strength. Different flour types are selected based on desired outcomes: bread flour for chewy loaves with good rise, cake flour for tender, delicate crumbs, and all-purpose flour for general versatility. Flour is also used for dusting, coating meats before pan-frying, and as a binding agent in various preparations.
