flour or rice flour or cornstarch
Wheat flour is a primary source of carbohydrates, B vitamins, and iron; whole wheat flour retains bran and germ for additional fiber and nutrients. Rice flour and cornstarch are carbohydrate-dense with minimal protein; brown rice flour retains more fiber than white rice flour.
About
Flour is a fine powder produced by grinding cereal grains, legumes, or other starchy plant material. Wheat flour, the most common variety globally, is made from milling the endosperm of wheat berries and contains gluten proteins that develop structure in baked goods. Flour varies by extraction rate (whole grain vs. refined), protein content, and grain source, affecting baking properties and nutritional composition.
Rice flour, produced by grinding white or brown rice, is naturally gluten-free and has a finer, more delicate texture than wheat flour. Cornstarch, derived from corn kernels, is a pure polysaccharide starch with minimal protein and no gluten, prized for its thickening properties and neutral flavor. These grain-based powders form the foundation of baked goods, thickening agents, and coating materials across global cuisines.
Culinary Uses
Flour serves as the primary dry ingredient in breads, cakes, pastries, and noodles, with protein content determining texture—high-protein flours suit bread-making, while lower-protein varieties work for cakes and pastries. Rice flour features prominently in Asian cuisine for noodles, dumpling wrappers, batters, and desserts, offering a tender crumb. Cornstarch functions primarily as a thickening agent in sauces, gravies, and desserts, and as a coating for fried foods to create crispness.
All three are used for dusting work surfaces, coating proteins before cooking, and creating roux-based sauces. Rice flour and cornstarch suit gluten-free baking and cooking when wheat flour must be avoided.
