On this page, corn flour refers to the fine starch powder extracted from corn, known as cornstarch in North America and maize starch in some other regions. It is commonly used as a thickening agent in sauces, gravies, soups, and custards, and can also be used in some baking recipes to soften texture. One metric cup of corn flour weighs approximately 135 grams.

Corn flour (cornstarch) is a very fine starch that compacts easily when scooped, so measuring by weight gives more accurate and consistent results than volume alone. This page lets you convert corn flour between grams, cups, tablespoons, and more so your recipes turn out reliably every time.

Related to Corn Flour

Arrowroot

Arrowroot swaps 1:1 for corn flour as a thickener and sets clearer, which suits glossy fruit glazes and acidic sauces. It thickens at a slightly lower temperature, so stir it in near the end and avoid a hard boil, which can thin it back out. See our Arrowroot converter.

Tapioca Starch

Tapioca starch swaps 1:1 for corn flour as a thickener and sets glossy and clear, holding up through freezing. Corn flour is cheaper and turns a sauce slightly cloudy. Blend either into cold liquid before heating to avoid lumps. See our Tapioca Starch converter.

Plain Flour

Plain flour thickens in place of corn flour but has about half the power, so use roughly twice as much. It clouds the sauce rather than setting it clear, and needs a few minutes longer cooking to lose the raw-flour taste. Whisk it in as a paste to avoid lumps. See our Plain Flour converter.

Cornmeal

Both are ground corn and the names sit one letter apart, which is where the trouble starts. Cornmeal is the whole kernel ground coarse, so it stays gritty and tastes of corn; corn flour is the starch on its own, fine and near flavourless. Thicken a sauce with cornmeal and it turns grainy. See our Cornmeal converter.
