Cornstarch is a versatile ingredient that finds its way into a myriad of recipes, from sauces and soups to desserts and baked goods. But what happens when you’ve run out of cornstarch and only have flour at your disposal? Can you create cornstarch using flour? In this article, we will explore the relationship between cornstarch and flour, discussing detailed steps on how to mimic cornstarch using flour, delving into practical uses, and understanding the science behind these ingredients.
The Essential Differences Between Cornstarch and Flour
Understanding how to make cornstarch with flour begins by appreciating the key differences between these two staples in the culinary world.
Cornstarch: A Pure Starch
Cornstarch is derived specifically from the endosperm of corn kernels. It is highly refined and primarily composed of amylose and amylopectin, which are types of starch. The properties of cornstarch give it unique capabilities in cooking and baking:
- Thickening Agent: Cornstarch is excellent for thickening sauces, gravies, and puddings.
- Texture Enhancer: It adds a silky smooth mouthfeel to dishes.
- Gluten-Free: As a naturally gluten-free product, cornstarch is perfect for those with gluten sensitivities.
Flour: A Complex Blend
On the other hand, flour, particularly wheat flour, contains proteins, starches, and dietary fiber. It is obtained by grinding grains and comes in various types, including all-purpose, whole wheat, and cake flour. The composition of flour affects its utility:
- Gluten Content: Flour contains gluten, which provides structure to baked goods.
- Browning Agent: Flour contributes to color and flavor during the baking process.
- Potential for Thickeners: Although flour can thicken, it doesn’t do so as efficiently as cornstarch.
Can You Make Cornstarch from Flour? The Truth Revealed
To answer the question, You cannot make cornstarch directly from flour. Cornstarch is a pure starch derived solely from corn, whereas flour contains proteins and gluten which differ significantly in processing and effectiveness when used to thicken recipes. However, there are ways to use flour as an alternative thickening agent when cornstarch isn’t available.
How to Use Flour Instead of Cornstarch
If you’re in a pinch and need a thickening agent, consider the following methods to use flour in a manner akin to cornstarch.
1. Flour Slurry
A flour slurry can be created by mixing flour with cold water before incorporating it into your dish. Here’s how to create one:
- Measure flour: Typically, use 2 tablespoons of flour for every 1 tablespoon of cornstarch called for in the recipe.
- Mix: Whisk the flour with cold water or broth until smooth and free of lumps.
- Combine: Gradually add the slurry into your hot liquid, stirring continuously to prevent clumping.
This method takes a bit longer to thicken than cornstarch but can be effective.
2. Cooking Method Adjustments
When using flour as a thickening agent:
Time Factor
Cooking flour requires more time to fully absorb and eliminate its raw flavor. Be prepared to simmer your dish longer once the flour is added.

What is cornstarch and how is it different from flour?
Cornstarch is a fine, white powder derived from the endosperm of corn kernels. It is primarily composed of carbohydrates and is used as a thickening agent in cooking, baking, and food preparation. Unlike flour, which contains gluten, cornstarch is gluten-free, making it suitable for various dietary restrictions. This unique composition gives cornstarch different properties, such as providing a glossy finish to sauces and a lighter texture to baked goods.
Flour, on the other hand, is ground from grains like wheat and contains proteins that can form gluten when mixed with water. This gluten structure gives baked goods their chewy texture. While both cornstarch and flour can be used in the kitchen, they serve distinct purposes, with cornstarch being favored for its thickening capabilities rather than for structure in baking.
Can you make cornstarch from flour?
While cornstarch and flour are both used as thickeners, they are fundamentally different products and cannot be directly converted from one to the other. You cannot make authentic cornstarch from regular flour because cornstarch is derived specifically from corn, whereas flour comes from grains like wheat. However, some people look for substitutes or alternatives that can mimic the function of cornstarch in recipes.
If you are in need of cornstarch for a recipe and only have flour available, you can use flour as a thickening agent, but it’s important to remember that it may not yield the same results. Generally, you’ll need to use a larger quantity of flour for thickening than you would of cornstarch, as flour does not have the same thickening efficiency.
What are some substitutes for cornstarch?
If you don’t have cornstarch on hand, there are several substitutes you can use in cooking and baking. Common alternatives include arrowroot powder, potato starch, and tapioca starch, all of which can act similarly to cornstarch in thickening sauces and gravies. Each of these substitutes has its own properties, so you may need to adjust quantities when using them in place of cornstarch.
You can also use flour as a substitute, although it alters the texture of the final product and may impart a slightly different flavor. Typically, you would need to use about twice the amount of flour as you would cornstarch. Another possibility is to use ground flaxseed or chia seeds, but these options are best for specific recipes and may not work well in every situation.
How do I thicken sauce with cornstarch?
Thickening a sauce with cornstarch is a straightforward process that involves creating a slurry. Start by combining equal parts of cornstarch and cold water, mixing until the cornstarch is fully dissolved. This prevents any lumps from forming when you add it to your sauce. Once your sauce is heated, gradually stir in the slurry while continuously whisking to ensure even distribution.
Essentially, allow the sauce to simmer for a few minutes after adding the cornstarch slurry, as this will give the cornstarch time to activate and thicken the sauce. Keep an eye on the consistency and remove it from heat once it reaches your desired thickness. Remember that overcooking can lead to a loss of thickening power, so it’s crucial to monitor the saucing process closely.
Can cornstarch be used for baking?
Yes, cornstarch can be used in baking, although its role differs from that of flour. It is often included in recipes to enhance the texture of baked goods, resulting in a more tender and delicate finish. Cornstarch is commonly used in combination with other types of flour, especially in recipes for cookies, cakes, and pastries where a light and airy texture is desired.
When substituting cornstarch in a baking recipe, it’s important to consider the overall balance of dry ingredients. A common practice is to replace a small portion of the flour with cornstarch to achieve the intended texture without compromising the baked good’s structure. This technique is particularly beneficial in achieving moist, soft cookies or delicate cakes.
How should I store cornstarch?
Proper storage of cornstarch is essential to maintain its effectiveness and quality. Cornstarch should be kept in a cool, dry place, ideally in an airtight container to protect it from moisture and humidity. If left exposed, it can clump and lose its thickening ability. A pantry or cupboard away from direct sunlight is an ideal spot for storing cornstarch.
Additionally, check the expiration date on your cornstarch package. While it typically has a long shelf life, exposure to air and moisture can affect its performance over time. If you notice any changes in color, smell, or texture, it’s best to discard it to ensure optimal results in your cooking and baking.
Can cornstarch be used as a gluten-free alternative?
Absolutely! Cornstarch is naturally gluten-free, which makes it an excellent choice for those with gluten sensitivities or celiac disease. It can be included in recipes that require thickening, such as soups, sauces, and gravies, without introducing any gluten-containing ingredients. This versatility allows for a wider variety of culinary options for individuals seeking a gluten-free diet.
Moreover, cornstarch can also be used in gluten-free baked goods, often in conjunction with other gluten-free flours to improve texture. When creating gluten-free recipes, combining cornstarch with flours like almond, coconut, or rice flour can help achieve a pleasing consistency that mimics traditional wheat-based products while remaining safe for gluten-sensitive individuals.
Is it necessary to heat cornstarch before using it?
In most instances, it is essential to heat cornstarch in order for it to activate and perform its thickening function. When cornstarch is mixed with cold liquid, it forms a slurry, which must then be heated to allow the starch granules to swell and absorb moisture. This interaction is what leads to the thickening result you see in sauces and soups.
If cornstarch is added to hot liquids directly, it can form clumps instead of thickening the mixture. Instead, always create a slurry with cold water first, then incorporate it into your hot dish while stirring. This technique ensures a smooth, lump-free outcome and maximizes the effectiveness of cornstarch in your cooking.
