GrainsYear-round. Flour is a shelf-stable, milled product that remains available consistently throughout the year, though wheat harvests occur seasonally (typically late summer to autumn in temperate regions).

Flour is primarily a source of carbohydrates and plant-based protein, with enriched varieties fortified with B vitamins and iron. Whole grain flours provide additional fiber and micronutrients compared to refined white flour.

About

Flour is a powder produced by grinding cereal grains, most commonly wheat (Triticum species), though it may also be derived from other grains such as rye, barley, oats, corn, or rice. The grinding process breaks down the grain kernel into fine particles, separating the starchy endosperm from the bran and germ, though whole grain flours retain all components.

Wheat flour, the most widely used variety, contains approximately 10-15% protein and significant amounts of carbohydrates and gluten, a network-forming protein that provides structure to baked goods. Flour is classified by protein content and milling method: all-purpose flour (10-12% protein), bread flour (12-14% protein), cake flour (7-9% protein), and pastry flour (9-10% protein). The color ranges from white to cream, and the texture is uniformly fine and powdery.

Culinary Uses

Flour is the foundational ingredient in baking and cooking, essential for breads, cakes, pastries, cookies, and thickening sauces and gravies. In bread-making, the protein content and gluten development determine crumb structure and elasticity. Different flour types are selected based on desired outcomes: bread flour for chewy, structured loaves; cake flour for tender crumb; and all-purpose flour for versatile everyday baking. Flour is also used in coating for frying, as a binder in meatballs and patties, and as a roux base for sauces across numerous culinary traditions. Beyond wheat, specialty flours including almond, buckwheat, and coconut flour serve gluten-free and alternative dietary applications.

Forms & Preparations

All-purpose flour — Refined wheat flour with 10-12% protein content; the most versatile flour for general baking, sauces, and coating.
Bread flour — High-protein wheat flour (12-14%) that develops strong gluten networks; ideal for yeasted breads and artisan loaves.
Cake flour — Low-protein, finely milled wheat flour (7-9%) that produces tender crumbs and is used primarily for cakes and soft pastries.
Whole wheat flour — Unrefined flour containing the entire wheat kernel (bran, germ, and endosperm); nuttier flavor and higher fiber than white flour.
Self-rising flour — All-purpose flour pre-mixed with leavening agents (baking powder and salt); used for quick breads and biscuits without additional leavening.
Specialty flours — Gluten-free, ancient grain, or legume-based flours (almond, coconut, buckwheat, chickpea) used for dietary restrictions and alternative applications.
