Roux sauce, a cornerstone of French cuisine, is a versatile base for countless sauces, soups, and stews. It’s a simple mixture of butter and flour cooked together, creating a thickener that can be further transformed with various ingredients. This article delves into the intricacies of roux sauce, exploring its history, types, applications, and techniques.
A Brief History of Roux
The origins of roux can be traced back to ancient Roman cuisine, where a similar mixture of flour and fat was used to thicken sauces. However, it was the French chefs of the 18th century who truly perfected the technique, incorporating roux into their refined culinary repertoire. The word “roux” itself is derived from the French verb “rouer,” meaning “to brown.”
Types of Roux
The type of roux used depends on the desired thickness and color of the final sauce. There are three primary types:
White roux: This is the most common type, made by cooking equal parts butter and flour over low heat until smooth and creamy. It has a neutral flavor and can be used for a variety of sauces, including béchamel, velouté, and curry.
Blonde roux: Cooked for a slightly longer time, a blonde roux develops a nutty flavor and a light brown color. It’s suitable for sauces like espagnole and demi-glace.
Brown roux: This type is cooked until dark brown and has a rich, earthy flavor. It’s often used as a base for pan sauces and gravies.
The Roux-Making Process
Creating a roux is a simple process, but it requires careful attention to prevent burning. Here’s a step-by-step guide:
Melt the butter: In a saucepan over medium heat, melt the butter until it is completely liquid.
Whisk in the flour: Gradually whisk in the flour, ensuring that there are no lumps.
Cook the roux: Cook the mixture, stirring constantly, until it reaches the desired color and thickness.
Add liquid: Gradually whisk in the desired liquid, such as milk, stock, or wine, until the sauce has reached the desired consistency.
Common Roux-Based Sauces
Roux is the foundation for many classic sauces in French cuisine. Some of the most common examples include:
Béchamel: A creamy white sauce made with white roux, milk, and nutmeg. It’s often used in lasagnas, croquettes, and soufflés.
Velouté: A light, delicate sauce made with white roux and a light stock, such as chicken or fish. It’s a versatile base for various sauces, including cream sauce and sauce Mornay.
Espagnole: A rich, brown sauce made with blonde roux, beef stock, mirepoix, and tomato paste. It’s the base for many pan sauces and gravies.
Demi-glace: A concentrated brown sauce made by reducing espagnole sauce. It’s a main component in many traditional French recipes.
Tips for Making Roux
Use a medium heat: Cooking the roux over too high a heat can cause it to burn.
Stir constantly: Consistent stirring prevents the roux from clumping and burning.
Add liquid gradually: Adding the liquid slowly ensures that the roux is fully incorporated into the sauce.
Adjust the flavor: The flavor of a roux-based sauce can be adjusted with herbs, spices, and other ingredients.
Roux in Modern Cuisine
While roux remains a staple in classic French cuisine, it has also found a place in modern culinary creations. Chefs around the world experiment with different ingredients and techniques to create unique roux-based sauces. For example, some chefs incorporate unusual flours, such as almond or chestnut, to add a distinctive flavor and texture.
Advanced Roux Techniques
Dark roux: For a truly intense flavor and deep color, cook the roux until it’s almost black. This type of roux is often used in rich, hearty dishes like beef stews and braises.
Beurre manié: This technique involves combining equal parts softened butter and flour into a paste. It’s a quick and easy way to thicken sauces without cooking a roux.
Roux brûlé: This involves burning the roux slightly to add a smoky flavor. It’s often used in sauces for grilled meats and seafood.
Troubleshooting Roux
Lumpy roux: If your roux is lumpy, it’s likely because you didn’t whisk in the flour gradually enough. To fix this, whisk in more liquid until the lumps dissolve.
Burnt roux: A burnt roux will have a bitter taste. Unfortunately, there’s no way to recover it. It’s best to start over with a new roux.
Too thick roux: If your roux is too thick, simply add more liquid.
Too thin roux: If your roux is too thin, cook it for a longer time to evaporate some of the liquid.
