Ingredients

  • 100 g all-purpose flour
  • 100 g unsalted butter

Steps

  1. Melt the butter in a heavy-bottomed skillet over medium heat until fully liquefied, about 2-3 minutes.

  2. Gradually whisk in the flour, ensuring there are no lumps, and maintain the heat at medium to avoid burning.

  3. Continue to stir the mixture constantly for about 10-15 minutes until it reaches a deep brown color, resembling chocolate.

  4. Remove from heat immediately once the desired color is achieved to prevent overcooking.

Why this works

Creating a brown roux involves carefully toasting flour in fat at a controlled temperature to develop a rich color and flavor. The Maillard reaction occurs as the flour cooks, resulting in a complex nutty taste and darker hue. This roux serves as a foundation for many sauces and soups, thickening and imparting depth. If the mixture seems too thick or lumpy, add a splash of warm water or stock while whisking to smooth it out. Conversely, if it turns too dark too quickly, reduce the heat immediately to slow down the cooking process and prevent burning, which can create an unpleasant bitterness.
