Making a roux is a fundamental technique in cooking that serves as a base for various sauces, soups, and stews. Traditionally, roux is made with flour and fat, such as butter or oil. However, with the increasing demand for gluten-free and innovative cooking methods, the question arises: can you make a roux with butter and cornstarch? In this article, we will delve into the world of thickening agents, explore the possibilities of using butter and cornstarch to make a roux, and discuss the benefits and limitations of this approach.
Understanding Roux and Its Traditional Ingredients
A roux is a mixture of fat and flour that is cooked together until it reaches a desired color, ranging from white to dark brown. The traditional ingredients for making a roux include flour, which provides the structure and thickening properties, and fat, which adds flavor and helps to cook the flour. The combination of these two ingredients creates a smooth, velvety texture that is essential for various culinary preparations.
The Role of Flour in Roux
Flour is a critical component of traditional roux, as it contains starches that gelatinize when heated, creating a network of molecules that trap liquid and thicken the mixture. The type of flour used can affect the color, texture, and flavor of the roux. For example, all-purpose flour is commonly used for white and blond roux, while bread flour or whole wheat flour may be used for darker roux.
Alternative Thickening Agents: Cornstarch
Cornstarch is a popular thickening agent that is derived from corn. It is composed of starch molecules that are easily gelatinized, making it an effective thickening agent. Cornstarch is often used in Asian cuisine and is a common substitute for flour in gluten-free cooking. When mixed with a liquid, cornstarch forms a slurry that can be added to hot mixtures to thicken them.

Can you make a roux with butter and cornstarch?
The traditional definition of a roux involves combining flour with fat, such as butter or oil, to create a mixture that is used to thicken sauces and soups. However, when it comes to using cornstarch as a thickening agent, the process is slightly different. Cornstarch is typically mixed with a cold liquid to create a slurry, which is then added to the sauce or soup to achieve the desired thickness. While it is technically possible to combine butter and cornstarch, it would not be considered a traditional roux.
In order to make a mixture with butter and cornstarch, you would need to mix the cornstarch with a cold liquid, such as water or broth, to create a slurry. Then, you could add the slurry to the melted butter and cook the mixture for a short period of time to remove any starchy flavor. However, this mixture would not have the same properties as a traditional roux, which is cooked for a longer period of time to develop a rich, nutty flavor and a smooth, velvety texture. If you’re looking for a substitute for traditional roux, it’s worth considering other options, such as using a different type of starch or thickening agent.
What is the difference between a roux and a slurry?
A roux and a slurry are two different thickening agents used in cooking, each with its own unique characteristics and uses. A roux is a mixture of flour and fat, such as butter or oil, that is cooked together to create a smooth, velvety paste. The cooking process can range from a few minutes to an hour or more, depending on the desired color and flavor of the roux. A slurry, on the other hand, is a mixture of a starch, such as cornstarch or flour, with a cold liquid, such as water or broth. The slurry is then added to the sauce or soup to achieve the desired thickness.
The main difference between a roux and a slurry is the way they are prepared and the resulting texture and flavor they impart to the dish. A roux is cooked for a longer period of time, which allows it to develop a rich, nutty flavor and a smooth, velvety texture. A slurry, on the other hand, is not cooked for as long and has a more neutral flavor. Roux is often used in dishes where a rich, thick texture is desired, such as in gumbo or mac and cheese. Slurry, on the other hand, is often used in dishes where a lighter, more delicate texture is desired, such as in sauces or soups.
How do you make a roux with butter and flour?
To make a roux with butter and flour, start by melting the butter in a saucepan over medium heat. Once the butter has melted, add the flour and whisk the mixture together to form a smooth paste. Cook the roux for a few minutes, stirring constantly, until it reaches the desired color and texture. The cooking time will depend on the type of roux you’re making, with white roux cooking for just a few minutes and dark roux cooking for up to an hour or more.
As you cook the roux, it’s essential to stir constantly to prevent the mixture from burning or developing lumps. You can use a whisk or a spoon to stir the roux, depending on your personal preference. It’s also important to cook the roux over medium heat, as high heat can cause the mixture to burn or cook too quickly. Once the roux has reached the desired color and texture, you can use it as a thickening agent in your favorite recipes. Simply whisk the roux into the sauce or soup, and cook the mixture for a few minutes until it has thickened to your liking.
Can you use cornstarch as a substitute for flour in a roux?
While it’s technically possible to use cornstarch as a thickening agent in place of flour, it’s not recommended to use it as a substitute in a traditional roux. Cornstarch has a different texture and flavor than flour, and it can impart a starchy, unpleasant flavor to the dish if not used correctly. Additionally, cornstarch is typically mixed with a cold liquid to create a slurry, which is then added to the sauce or soup to achieve the desired thickness.
If you’re looking for a gluten-free substitute for flour in a roux, there are other options available that may be more suitable. For example, you can use gluten-free flours, such as rice flour or almond flour, to make a roux. These flours can be used in place of traditional flour to create a roux that is similar in texture and flavor. However, it’s essential to note that gluten-free flours can behave differently than traditional flour, so you may need to adjust the cooking time and technique to achieve the desired results.
How do you store a roux for later use?
If you’ve made a large batch of roux and want to store it for later use, there are a few options available. One of the simplest ways to store roux is to let it cool completely, then transfer it to an airtight container and refrigerate it. The roux can be stored in the refrigerator for up to a week, and it can be frozen for up to six months. When you’re ready to use the roux, simply thaw it overnight in the refrigerator or reheat it in a saucepan over low heat.
It’s essential to store the roux in an airtight container to prevent it from absorbing odors or flavors from other foods in the refrigerator. You can also add a layer of fat, such as butter or oil, to the top of the roux to prevent it from drying out or developing off-flavors. When reheating the roux, be sure to stir it constantly to prevent it from burning or developing lumps. You can also use the roux as a base for other sauces or soups, such as gumbo or mac and cheese.
What are some common mistakes to avoid when making a roux?
When making a roux, there are several common mistakes to avoid in order to achieve the best results. One of the most common mistakes is not cooking the roux for a long enough period of time, which can result in a roux that is too pale or has a starchy flavor. Another mistake is not stirring the roux constantly, which can cause it to burn or develop lumps. It’s also essential to use the right type of flour and fat, as different types can impart different flavors and textures to the roux.
To avoid these mistakes, it’s essential to follow a few simple guidelines. First, use a high-quality flour and fat, such as butter or oil, to make the roux. Second, cook the roux over medium heat, stirring constantly, until it reaches the desired color and texture. Third, be patient and don’t rush the cooking process, as a good roux takes time to develop.
