P.S. I use the roux method for this mac and cheese.

Creating the perfect roux is essential for many dishes, not just mac and cheese. Here are five steps to help you make the best roux:

  1. Choose your fat: Start by melting your fat of choice, typically butter or oil, in a heavy-bottomed saucepan over medium heat. The fat will act as the base for your roux and help thicken your sauce.
  2. Add equal parts flour: Once your fat is melted and hot, gradually add an equal amount of flour to create a paste-like mixture. For example, if you melted 2 tablespoons of butter, add 2 tablespoons of flour. Stir continuously to combine the flour and fat evenly.
  3. Cook to desired color: Continue cooking the flour and fat mixture, stirring constantly, until it reaches your desired level of color. A white roux is cooked just until the raw flour taste is gone and remains pale in color, while a blond roux develops a slightly nutty aroma and a light golden color. For a darker roux with a richer flavor, cook until it becomes caramel-colored, but be careful not to burn it.
  4. Adjust heat as needed: Keep an eye on the heat throughout the cooking process to prevent burning. If the roux starts to smoke or smell burnt, lower the heat immediately and continue stirring.
  5. Incorporate into your recipe: Once your roux reaches the desired color, remove it from the heat and immediately incorporate it into your recipe. Gradually whisk in liquid, such as broth or milk, to create a smooth consistency, and continue cooking until thickened to your liking.
