Preparation method

  • Weigh the flour and butter.
  • Heat the butter in a saucepan until it stops bubbling and allow the butter to brown. Remove the pan from the heat.
  • Add the flour and use a spatula to stir it through the melted butter. Keep the roux moving to prevent it from sticking to the bottom of the pan.
  • Bring the liquid to the boil whilst stirring and boil for a few minutes. This gives the roux maximum thickening properties and removes the floury taste.
  • Cook the roux on low heat. The roux is ready when the butter no longer seeps from the flour. This will take approximately three minutes. (The roux must be heated to 95ºC so that the starch can absorb all the liquid.)
  • If you’re working with a warm liquid, allow the roux to cool in refrigerator or freezer. If you’re working with a cold liquid, you can use the roux immediately.
  • Add the liquid, such as stock or milk, to the roux in three parts. Whisk until the mixture is smooth.
  • Continue boiling the sauce for five minutes until you can no longer taste the flour.
