-.8 c. flour

Flour is a powder produced by grinding cereal grains, most commonly wheat, into fine particles. The term derives from the Latin "flos" (flower), referencing its fine, powdery texture. Wheat flour is classified by protein content and milling method: all-purpose flour (10-12% protein) balances structure and tenderness; bread flour (12-14% protein) develops strong gluten networks; pastry and cake flours (7-9% protein) produce tender crumbs; and whole wheat flour retains the bran and germ, offering deeper flavor and nutrition but denser results.\n\nFlour serves as the foundational binder and structure-builder in countless preparations. The protein glutenin and gliadin form gluten when hydrated and agitated, providing elasticity and strength. Beyond wheat, flours are milled from barley, rye, oats, corn, rice, and numerous alternative grains and legumes, each with distinct baking properties and flavor profiles.

Flour functions as the primary dry ingredient in breads, pastries, cakes, cookies, and other baked goods, where its proteins develop gluten networks that trap gas and provide structure. It also serves as a thickening agent in sauces, gravies, and roux-based preparations, and as a coating for fried foods and vegetables. Beyond baking and cooking, flour appears in pasta doughs, batters, and dredging mixtures across cuisines worldwide. Selection of flour type fundamentally affects outcomes: bread flour yields chewy loaves with strong crumb, while cake flour produces tender, fine-crumbed desserts. Proper storage in cool, dry conditions preserves quality and prevents rancidity, particularly with whole grain varieties.
