What To Know
- It is also a good choice for sauces that will be heated over a long period of time, as it does not break down as easily as cornstarch.
- It is also a good choice for sauces that will be served cold, as it does not gel as easily as potato flour.
- Yes, you can substitute potato flour for cornstarch in a recipe, but you will need to use about twice as much potato flour to achieve the same consistency.
When it comes to thickening sauces, soups, and gravies, two common ingredients come to mind: potato flour and cornstarch. Both are derived from starchy plants, but they have distinct properties that make them suitable for different culinary applications. In this blog post, we will explore the key differences between potato flour and cornstarch, so you can make an informed decision about which one to use in your next recipe.
Origins and Composition
Potato flour, as the name suggests, is made from dehydrated potatoes. It is a fine, white powder that is high in starch content. Cornstarch, on the other hand, is derived from corn kernels. It is also a fine, white powder, but it has a slightly finer texture than potato flour.
Nutritional Value
Potato flour is a good source of carbohydrates and fiber, while cornstarch is primarily composed of carbohydrates. Potato flour also contains small amounts of protein and vitamins, such as vitamin C and vitamin B6.
Thickening Properties
Both potato flour and cornstarch are effective thickening agents, but they have different characteristics. Potato flour has a stronger thickening power than cornstarch, meaning that you will need to use less of it to achieve the same consistency. However, potato flour tends to create a thicker, more viscous sauce, while cornstarch produces a lighter, more transparent sauce.
Taste and Texture
Potato flour has a neutral taste and will not alter the flavor of your dish. However, it can add a slightly grainy texture if not cooked properly. Cornstarch, on the other hand, has a slightly sweet taste and can add a glossy sheen to your sauce. It produces a smooth, velvety texture.
Culinary Applications
Potato flour is best suited for dishes that require a thick, opaque sauce, such as stews, soups, and gravies. It is also a good choice for sauces that will be heated over a long period of time, as it does not break down as easily as cornstarch. Cornstarch is ideal for dishes that require a lighter, more transparent sauce, such as stir-fries, sauces, and glazes. It is also a good choice for sauces that will be served cold, as it does not gel as easily as potato flour.
Which One to Choose?
The choice between potato flour and cornstarch depends on the desired consistency and flavor of your dish. If you want a thick, opaque sauce with a neutral taste, then potato flour is a good option. If you prefer a lighter, more transparent sauce with a slightly sweet taste, then cornstarch is a better choice.
Additional Considerations
- Gluten: Potato flour is gluten-free, while cornstarch is not. If you have a gluten intolerance or celiac disease, then potato flour is the better choice.
- Availability: Potato flour may not be as readily available as cornstarch, especially in smaller grocery stores. However, it can be found in most health food stores and online retailers.
- Cost: Potato flour is typically more expensive than cornstarch.

Yes, you can substitute potato flour for cornstarch in a recipe, but you will need to use about twice as much potato flour to achieve the same consistency.
2. How do I cook with potato flour?
Potato flour should be mixed with a small amount of cold liquid before adding it to your sauce. This will help to prevent it from clumping. You can then bring the sauce to a simmer and cook until it reaches the desired consistency.
3. How do I cook with cornstarch?
Cornstarch can be added directly to your sauce. However, it is important to whisk it constantly to prevent it from clumping. You can then bring the sauce to a boil and cook until it reaches the desired consistency.
4. Which is better for baking, potato flour or cornstarch?
Cornstarch is generally preferred for baking, as it produces a lighter, more delicate texture. Potato flour can be used in baking, but it may result in a denser, more crumbly texture.
5. Can I use potato flour to make bread?
Yes, potato flour can be used to make bread. However, it is not a gluten-free flour, so it is not suitable for people with celiac disease or gluten intolerance.
