¹/₂ c flour

Flour is a powder produced by grinding cereal grains, legumes, or other starchy plant materials into fine particles. In culinary contexts, wheat flour is the most common form, derived from the endosperm of the wheat kernel (Triticum species) and milled to varying degrees of fineness. Flour serves as a fundamental binding and structural agent in baking and cooking, with protein content varying by grain type and milling process—ranging from soft wheat flour (6-9% protein) suitable for pastries to hard wheat flour (12-14% protein) ideal for bread-making.

The production of flour involves cleaning, tempering, and grinding grains between large stone or steel rollers, followed by sifting to achieve uniform particle size. Beyond wheat, flour may be produced from alternative grains such as rye, barley, oats, and corn, as well as legumes (chickpea flour) and nuts (almond flour), each imparting distinct flavor profiles and functional properties.

Flour is the primary dry ingredient in bread, pastries, cakes, cookies, and pasta, providing structure through gluten development and starch gelatinization during baking. It functions as a thickening agent in sauces and gravies and serves as a coating for proteins prior to sautéing. Different flour types are selected based on application: cake flour for delicate crumbs, bread flour for open crumb structure, and all-purpose flour for versatile baking. Specialty flours—such as whole wheat, rye, or alternative grain flours—are incorporated for nutritional enhancement or distinctive flavor contributions in specific regional cuisines.
