Corn flour vs. cornstarch: the key differences and when to use which
What To Know
- Corn flour is primarily used in baking and making tortillas, while cornstarch is used as a thickening agent in sauces, soups, and gravies.
- If you are replacing corn flour with cornstarch in a sauce or gravy, you will need to use about twice as much cornstarch to achieve the same level of thickening.
- Cornstarch can be used to make a cornstarch slurry, which is a mixture of cornstarch and water used to thicken sauces and gravies.
Corn flour and cornstarch, two commonly used ingredients in cooking and baking, are often confused due to their similar names and appearance. While they share some similarities, they are not interchangeable in all applications. This article will delve into the differences between corn flour and cornstarch and provide a comprehensive guide on when and how you can replace one with the other.
What is Corn Flour?
Corn flour, also known as cornmeal, is a finely ground powder made from dried corn kernels. It is a staple ingredient in many traditional dishes, particularly in Latin American and Southern American cuisines. Corn flour has a distinct yellow color and a coarse texture similar to wheat flour.
What is Cornstarch?
Cornstarch, on the other hand, is a refined starch extracted from the endosperm of corn kernels. It is a white, powdery substance with a fine texture that is commonly used as a thickening agent in sauces, soups, and gravies. Cornstarch has a neutral flavor and does not impart any color to the dish.
Similarities Between Corn Flour and Cornstarch
- Both corn flour and cornstarch are derived from corn.
- They are both starch-based and can be used as thickening agents.
Differences Between Corn Flour and Cornstarch
- Texture: Corn flour has a coarse texture, while cornstarch has a fine texture.
- Color: Corn flour is yellow, while cornstarch is white.
- Flavor: Corn flour has a slightly sweet, corn-like flavor, while cornstarch has a neutral flavor.

Can I Replace Corn Flour with Cornstarch?
Yes, you can replace corn flour with cornstarch in some applications. However, it is important to note that they are not perfect substitutes. Here are some guidelines to follow:
- In baking: Corn flour can be substituted for cornstarch in a 1:1 ratio in most baking recipes. However, it may result in a slightly denser and coarser texture.
- As a thickening agent: Cornstarch is a more effective thickening agent than corn flour. If you are replacing corn flour with cornstarch in a sauce or gravy, you will need to use about twice as much cornstarch to achieve the same level of thickening.
- In tortillas: Corn flour is not a suitable substitute for corn flour in tortillas. Corn flour is essential for the dough’s structure and texture.
When to Use Corn Flour
- Baking cornbread, muffins, and other corn-based baked goods
- Making tortillas and other corn-based dishes
- As a coating for fried foods

- For cornstarch: Arrowroot powder, tapioca starch, or potato starch
Tips for Using Corn Flour and Cornstarch
- Always whisk cornstarch into a small amount of liquid before adding it to the main dish to prevent clumping.
- Corn flour can be used to make polenta, a creamy cornmeal porridge.
- Cornstarch can be used to make a cornstarch slurry, which is a mixture of cornstarch and water used to thicken sauces and gravies.
Wrapping Up
