and one-fourth cups all purpose or unbleached flour
All-purpose flour is a good source of carbohydrates and provides B vitamins (especially thiamine and niacin), though enriched varieties often have added B vitamins and iron. It is relatively low in fiber compared to whole wheat flour.
About
All-purpose flour is a finely milled powder produced from the endosperm of wheat grains (Triticum aestivum), typically a blend of hard and soft wheat varieties. It is the most versatile flour in Western baking and cooking, containing approximately 10-12% protein content, which strikes a balance between the high-protein bread flours and low-protein cake flours. All-purpose flour is refined, meaning the bran and germ have been removed, leaving primarily starch and gluten-forming proteins. Unbleached varieties undergo minimal chemical treatment, while bleached versions use chemical agents to whiten the flour and slightly modify its baking properties.
All-purpose flour serves as the foundation for countless baked goods and thickening agents across cuisines. Its protein content creates moderate gluten development, making it suitable for breads, cakes, pastries, and other applications without the specialized performance requirements of single-purpose flours.
Culinary Uses
All-purpose flour is the standard flour for general baking, used in bread doughs, cakes, cookies, pastries, biscuits, and pie crusts. It functions as a thickening agent in sauces and gravies, and serves as a dusting and breading medium for proteins and vegetables. In savory cooking, it is essential for roux-based sauces in French cuisine and countless other culinary traditions. The moderate protein content allows home cooks and professional bakers to achieve a wide range of textures: from tender cakes to chewy breads, depending on hydration, mixing method, and technique. All-purpose flour is also used for dredging meats, thickening soups, and as a base for homemade pasta.
