The art of making the perfect gravy is a cornerstone of culinary expertise, elevating dishes from mundane to sublime. Two common thickeners used in gravy preparation are flour and cornflour. While both can serve the purpose, they have different properties and uses. The question of whether you can use flour instead of cornflour for gravy is one that has puzzled many a cook. In this article, we delve into the details of using flour as a substitute for cornflour in gravy, exploring the science, techniques, and outcomes.
Understanding Flour and Cornflour
Before substituting flour for cornflour, it’s essential to understand the characteristics of each. Flour, typically made from wheat, is a staple in baking and cooking. It contains proteins, which contribute to its thickening properties when mixed with liquids. Cornflour, on the other hand, is derived from corn and is known for its finer texture and neutral flavor. It is predominantly starch, which makes it an excellent thickener without affecting the flavor profile of dishes.
The Science of Thickening
The process of thickening with flour or cornflour involves the absorption of liquid by the starches, which then swell and thicken the mixture. Flour requires cooking to remove the raw taste and to achieve the desired consistency, whereas cornflour can often be added directly to cold liquids and then heated to avoid lumps. This fundamental difference impacts the method and outcome of using flour versus cornflour in gravy.
Practical Applications
In practical terms, when deciding to use flour instead of cornflour, consider the flavor and texture you aim to achieve. Flour can impart a slightly nutty, cooked flavor that some find desirable in certain types of gravy, but it may not be appropriate for all recipes. The texture, too, can be slightly heavier with flour due to its protein content, which can be beneficial in heartier, more rustic gravies.
Making Gravy with Flour
To use flour as a thickener for gravy effectively, follow a few key steps:
Step 1: Mixing the Roux
Begin by creating a roux, a mixture of flour and fat (such as butter or oil), cooked until it reaches the desired color, from pale (for lighter sauces) to darker (for richer, nuttier flavors). This step is crucial as it enhances the flavor and ensures the flour is cooked, thus preventing a raw flour taste in your gravy.
Step 2: Adding Liquid
Gradually add your liquid (stock, broth, or wine) to the roux, whisking continuously to prevent lumps. The key here is to add the liquid slowly, allowing each portion to be fully incorporated before adding more. This method helps in achieving a smooth, even consistency.
Step 3: Seasoning and Reduction
Once you’ve added all your liquid, bring the mixture to a simmer. Season with salt, pepper, and any other desired herbs or spices. If the gravy is too thin, continue to simmer until it reaches your desired consistency. Reduction is a powerful technique for concentrating flavors and thickening the gravy.
Comparing Outcomes: Flour vs. Cornflour Gravy
The choice between flour and cornflour for gravy ultimately comes down to personal preference and the specific requirements of your dish. Flour-based gravies tend to be heartier and more flavorful, with a potential for a nuttier taste if the roux is cooked longer. On the other hand, cornflour provides a lighter, more neutral thickening that won’t alter the inherent flavors of your dish.
Texture and Appearance
Texture and appearance are also significant factors. Flour-based gravies can sometimes appear cloudy due to the fat content in the roux, whereas cornflour gravies are generally clearer. The texture of flour gravy can feel richer and more velvety, especially if a darker roux is used, while cornflour gravies are typically smoother and lighter.
Tips for Successful Substitution
If you decide to substitute flour for cornflour, keep the following tips in mind:
- Use a fine, all-purpose flour for the best results, as it will mix more easily and provide a smoother texture.
- Adjust the amount of flour according to your gravy’s desired thickness. Generally, you’ll need less flour than cornflour because flour swells more when cooked.
- Be patient and whisk constantly when adding liquid to the roux to avoid lumps, ensuring a smooth gravy.
Culinary Versatility
The versatility of using flour in gravy preparation lies in its adaptability to various cuisines and dishes. From traditional roast dinners to innovative fusion dishes, flour can be used to create gravies that are both authentic and unique. Experimenting with different types of flour, such as whole wheat or ancient grain flours, can also add layers of depth and complexity to your gravies.
Conclusion on Substitution
In conclusion, while cornflour is often preferred for its ease of use and neutral taste, flour can indeed be used as a substitute in gravy, offering a rich, full-bodied alternative. By understanding the properties of flour and cornflour, and applying the right techniques, you can create gravies that not only thicken beautifully but also enhance the overall dining experience.
Final Thoughts and Recommendations
The world of cooking is full of substitutions and alternatives, each offering unique advantages. When it comes to using flour instead of cornflour for gravy, the key is to understand the science behind the thickening process and to apply practical techniques for the best outcomes. Whether you’re a seasoned chef or an enthusiastic home cook, experimenting with different thickeners and methods can lead to new flavors and textures that elevate your dishes.
In the realm of gravy making, there’s no one-size-fits-all solution. Flour and cornflour both have their places, and the choice between them should be based on the specific needs and goals of your recipe. With practice and patience, you’ll find that using flour as a thickener can open up new possibilities for creating delicious, memorable gravies that complement a wide range of dishes.
What is the main difference between flour and cornflour in gravy making?
The main difference between flour and cornflour in gravy making lies in their starch composition and how they interact with liquid. Flour is made from wheat and contains a mixture of starch, protein, and fiber, which can make it more prone to forming lumps when mixed with liquid. On the other hand, cornflour is made from corn and is primarily composed of starch, making it a more effective thickening agent. Cornflour is also more finely milled than flour, which allows it to dissolve more easily in liquid and create a smoother texture.
When using flour as a substitute for cornflour in gravy, it is essential to note that the ratio of flour to liquid may need to be adjusted. A general rule of thumb is to use about 1 1/2 to 2 times more flour than cornflour to achieve the same thickening effect. Additionally, it is crucial to mix the flour with a small amount of cold water or broth before adding it to the hot gravy to prevent lumps from forming. By taking these precautions, you can still achieve a rich and creamy gravy using flour, although it may not be as smooth as one made with cornflour.
Can I use all-purpose flour as a direct substitute for cornflour in gravy recipes?
While it is possible to use all-purpose flour as a substitute for cornflour in gravy recipes, it is not always the best option. All-purpose flour contains a higher protein content than cornflour, which can affect the texture and flavor of the gravy. The gluten in the flour can also make the gravy more prone to thickening unevenly or becoming too thick. However, if you only have all-purpose flour on hand, you can still use it to make a decent gravy. It is essential to use a gentle heating process to prevent the flour from forming lumps and to stir constantly to ensure the gravy thickens evenly.
To minimize the risks associated with using all-purpose flour, it is recommended to use a combination of flour and fat (such as butter or oil) to make a roux before adding the liquid. This helps to cook out the raw flour taste and prevents lumps from forming. It is also crucial to whisk the mixture constantly and cook it for a sufficient amount of time to achieve the desired consistency. By taking these precautions, you can still make a delicious and savory gravy using all-purpose flour, although it may not be as smooth as one made with cornflour.
What are the benefits of using cornflour instead of flour in gravy making?
The primary benefit of using cornflour instead of flour in gravy making is its ability to thicken liquids without affecting their flavor or texture.

Additionally, cornflour is less likely to form lumps than flour, which can be a major advantage when working with hot liquids. Cornflour also has a higher thickening power than flour, which means you need to use less of it to achieve the same effect.
Another significant benefit of using cornflour is its ability to withstand high temperatures without breaking down or losing its thickening properties. This makes it an ideal ingredient for making gravies and sauces that need to be simmered or boiled for extended periods. In contrast, flour can break down and lose its thickening power when exposed to high temperatures, resulting in a thin or watery consistency. Overall, cornflour is a more reliable and efficient thickening agent than flour, making it a popular choice among cooks and chefs.
How do I mix flour with liquid to avoid lumps when making gravy?
To mix flour with liquid and avoid lumps when making gravy, it is essential to use a gentle and gradual process. Start by mixing a small amount of flour with a cold liquid, such as water or broth, to form a smooth paste. This is often referred to as a “slurry.” The cold liquid helps to prevent the flour from forming lumps, and the smooth paste can then be added to the hot gravy without causing any issues. It is crucial to whisk the slurry constantly and cook it for a sufficient amount of time to achieve the desired consistency.
When adding the slurry to the hot gravy, it is essential to whisk constantly and gently to prevent lumps from forming. You can also temper the slurry by slowly pouring the hot gravy into the slurry while whisking constantly. This helps to prevent the flour from seizing up and forming lumps. By following these steps, you can mix flour with liquid without forming lumps and achieve a smooth and creamy gravy. It is also important to note that using a roux or cooking the flour in fat before adding the liquid can also help to prevent lumps and ensure a smooth texture.
Can I use self-raising flour as a substitute for cornflour in gravy recipes?
While it is technically possible to use self-raising flour as a substitute for cornflour in gravy recipes, it is not the best option. Self-raising flour contains baking powder, which is designed to release gas and cause baked goods to rise. In the context of gravy making, the baking powder can cause the gravy to become foamy or bubbly, which can be undesirable. Additionally, self-raising flour may contain other ingredients, such as salt or sugar, that can affect the flavor of the gravy.
If you only have self-raising flour on hand, you can still use it to make a decent gravy. However, it is essential to use a reduced amount of self-raising flour compared to cornflour, as the baking powder can cause the gravy to thicken more quickly. It is also crucial to whisk the mixture constantly and cook it for a sufficient amount of time to achieve the desired consistency. To minimize the risks associated with using self-raising flour, you can also try to remove some of the baking powder by sifting the flour or using a small amount of plain flour to balance out the mixture.
What are the common mistakes to avoid when using flour as a thickening agent in gravy?
One of the most common mistakes to avoid when using flour as a thickening agent in gravy is not mixing the flour with a cold liquid before adding it to the hot gravy. This can cause the flour to form lumps, resulting in an uneven texture. Another mistake is not cooking the flour for a sufficient amount of time, which can result in a raw or starchy flavor.
