Flour is known as wheat flour, all-purpose flour, ap flour, plain flour, wheat, and all purpose flour.
Turns tender and structured in baked goods, silky when cooked into a roux or sauce, crisp when fried as a coating.
Flour is the backbone of baking and a common thickener for sauces and gravies. Mix with fat for a roux, or coat food before frying for crunch. Store in a sealed container somewhere cool and dry. Pairs with butter, eggs, and yeast in most doughs.
Flour has low water content. Doesn't add much moisture; batters may need liquid elsewhere.
Builds structure through gluten and starch. Base for bread, cakes, and pastry. Amount and type set crumb and chew.
Used to coat meat or vegetables before the pan for a browned crust. Also thickens pan sauces and gravies.
Coats food for crisp, golden crusts. Absorbs oil if the batter's too thick or the oil's too cool.
Thickens stews and braises when mixed into a paste or roux first. Prevents lumps if whisked in slowly.
Works in steamed buns, dumplings, and puddings where gentle moist heat sets the starch and gluten structure.
Occasionally used to thicken hot drinks or as a base for roux in savory drink bases like congee gravies.
Not used directly on the grill. Only relevant if food was floured beforehand and finished over flame.
Not eaten raw. Contains raw starch and proteins that taste chalky and can carry food safety risks.
