The floury dilemma: corn flour vs. cornstarch – can they swap?
What To Know
- Corn flour is a finely ground cornmeal, while cornstarch is a pure starch extracted from corn.
- However, it is important to note that you will need to use about twice as much corn flour as cornstarch to achieve the desired thickening.
- Can be used as a substitute for corn flour or cornstarch in most recipes.
In the world of baking, corn flour and cornstarch are often used interchangeably. However, these two ingredients are not exactly the same. Corn flour is a finely ground cornmeal, while cornstarch is a pure starch extracted from corn. This difference in composition leads to some key distinctions in their properties and uses.
Understanding the Differences
1. Texture: Corn flour has a coarser texture than cornstarch, resulting in a grittier mouthfeel. Cornstarch, on the other hand, is smooth and velvety.
2. Thickening Properties: Corn flour is a weaker thickener than cornstarch. It requires more to achieve the same level of thickening.
3. Flavor: Corn flour has a slightly corn-like flavor, while cornstarch is relatively flavorless.
Substitution Guidelines
1. Can I Substitute Corn Flour for Cornstarch?
Yes, you can substitute corn flour for cornstarch in some cases. However, it is important to note that you will need to use about twice as much corn flour as cornstarch to achieve the desired thickening. This is because corn flour is less concentrated in starch.
2. Can I Substitute Cornstarch for Corn Flour?
It is not recommended to substitute cornstarch for corn flour in most cases. Cornstarch will not provide the same texture or flavor as corn flour.
When to Use Corn Flour vs. Cornstarch

Alternative Thickening Agents
If you do not have corn flour or cornstarch on hand, you can use other thickening agents such as:
- Wheat flour: Can be used as a substitute for corn flour or cornstarch in most recipes.
- Arrowroot powder: A gluten-free starch that is slightly less thickening than cornstarch.
- Potato starch: Another gluten-free starch that is comparable in thickening power to cornstarch.
Recommendations: Navigating the Corn Flour vs. Cornstarch Dilemma
Understanding the differences between corn flour and cornstarch is crucial for achieving the desired results in your baking and cooking endeavors. By following the guidelines outlined above, you can confidently substitute these ingredients when necessary. Remember, it is always best to use the ingredient specified in the recipe for optimal flavor and texture.
