Flour is a fine powder produced by grinding cereal grains, most commonly wheat, into a uniform, powder-like consistency. The primary grain source for flour in Western cooking is common wheat (Triticum aestivum), though flour can also be milled from barley, rye, rice, maize, and other grain crops. The grain kernel is composed of three anatomical parts: the outer bran layer (containing fiber and nutrients), the starchy endosperm (the majority of the kernel), and the nutrient-rich germ. All-purpose flour, the most versatile and widely used variety, typically contains 10-12% protein and represents a blend of hard and soft wheat varieties that balance gluten development with versatility across applications. Specialty flours—such as bread flour (higher protein content for gluten development), cake flour (lower protein for tender crumbs), whole wheat flour (retains bran and germ), and self-rising flour (pre-mixed with leavening agents)—are formulated for specific baking and cooking purposes.

Flour serves as a fundamental binding and structural ingredient across global cuisines, forming the base for breads, pastries, cakes, and numerous sauces. In bread-making, flour's gluten proteins hydrate and develop into networks that trap carbon dioxide and create structure. Beyond baking, flour functions as a thickening agent in roux and gravies, a coating for fried foods, and a binding component in batters and dough-based preparations. Different flour types are selected based on desired outcomes: bread flour for chewy, well-risen loaves; cake flour for tender, fine-crumbed cakes; whole wheat flour for nutty flavor and fiber in rustic baked goods; and all-purpose flour for everyday applications spanning cookies, quick breads, and composite dishes across cuisines from Italian pasta-making to Asian noodle production.
