Roux: The Classic Thickening Agent

Roux is a mixture of flour and fat (butter or oil) that's cooked together to create a smooth, velvety paste. This classic thickening agent is a staple in many French and Italian recipes, and for good reason. When cooked properly, roux can thicken sauces to the perfect consistency without adding any unwanted flavors or textures. To make roux, simply melt 1-2 tablespoons of fat in a pan over medium heat, then gradually add 1-2 tablespoons of flour, whisking continuously to prevent lumps.

Additionally, roux can be made ahead of time and stored in the fridge or freezer for later use. However, keep in mind that roux can be high in calories and fat, so be mindful of your portion sizes when using this thickening agent.

Tips and Variations:
• Use a combination of butter and oil to create a lighter-colored roux.
• Add a pinch of salt to the roux to enhance the flavors.
• Experiment with different types of flour, such as whole wheat or almond flour, for unique flavor profiles.
