Corn flour vs. cornstarch: the ultimate guide to substitutions

Corn flour and cornstarch are both derived from corn, but they are not interchangeable ingredients. Corn flour is a finely ground whole cornmeal, while cornstarch is a pure starch extracted from the endosperm of the corn kernel. This difference in composition results in different culinary properties.

Understanding Corn Flour

Corn flour is a versatile ingredient that can be used in various applications, including:

• Baking: Corn flour adds a subtle corn flavor and a slightly grainy texture to baked goods. It is commonly used in cornbread, muffins, and pancakes.
• Thickening: Corn flour can be used as a thickening agent for sauces, gravies, and soups. It provides a smooth, glossy consistency.
• Coating: Corn flour can be used to coat meat or vegetables before frying or baking. It creates a crispy, golden-brown crust.

Understanding Cornstarch

Cornstarch is a pure starch that is primarily used as a thickening agent. It is commonly used in:

• Sauces and Gravies: Cornstarch is the preferred thickener for sauces and gravies because it creates a clear, glossy finish.
• Soups: Cornstarch can be used to thicken soups and stews, providing a smooth, velvety texture.
• Puddings and Custards: Cornstarch is an essential ingredient in puddings and custards, giving them their creamy, thick consistency.

Can I Substitute Corn Flour for Cornstarch?

While corn flour and cornstarch share some similarities, they are not direct substitutes for each other. Here are the key differences to consider:

• Thickening Power: Cornstarch has a higher thickening power than corn flour. One tablespoon of cornstarch is equivalent to two tablespoons of corn flour.
• Taste: Corn flour has a slightly sweet, corn-like flavor, while cornstarch is flavorless.
• Texture: Corn flour adds a slight grainy texture to baked goods, while cornstarch provides a smooth, glossy consistency.
