cup all-purpose flour

All-purpose flour is a refined wheat flour milled from a blend of hard and soft wheat varieties, representing the most versatile flour type in Western baking and cooking. Produced by grinding the endosperm of wheat kernels and removing the bran and germ, all-purpose flour typically contains 10-12% protein and is enriched with vitamins and minerals in most commercial products. The neutral flavor profile and moderate gluten content make it suitable for a wide range of applications from tender cakes to chewy breads, though it represents a compromise rather than an optimization for any single application. Most commercial all-purpose flours are bleached or unbleached, with bleaching agents affecting the flour's oxidation and gluten development properties.

All-purpose flour serves as the foundation for countless Western baked goods including cakes, cookies, quick breads, biscuits, pie crusts, and everyday bread recipes. It is also used as a thickening agent in sauces and gravies, as a coating for fried foods, and in batters for pancakes and waffles. Beyond baking, it functions as a dusting flour for work surfaces and as a component in spice rubs. The moderate protein content allows for sufficient gluten development in yeast breads while remaining tender enough for pastries and cakes, making it the default choice for home bakers and commercial applications requiring a single all-purpose flour.
