Can Corn Flour Be Used Instead of Cornstarch?

The answer to this question depends on the specific application.

Baking

In baking, cornstarch is typically used as a thickening agent in sauces, gravies, and custards. It can also be used as a coating for fried foods. Corn flour can be used as a substitute for cornstarch in these applications, but it may produce a slightly different texture and flavor.

Cooking

In cooking, cornstarch is used as a thickener for soups, stews, and sauces. It can also be used to make a cornstarch slurry, which is a mixture of cornstarch and water used to thicken sauces and gravies. Corn flour can be used as a substitute for cornstarch in these applications, but it may result in a slightly thicker, more opaque texture.

Frying

Cornstarch is commonly used as a coating for fried foods, such as chicken and fish. It creates a crispy, golden-brown exterior. Corn flour can also be used as a coating, but it may produce a slightly different texture and flavor.
