Ingredients

The following ingredients have 4 Servings
  • 1 tbsp olive oil
  • 1 heaped tbsp flour (all-purpose)
  • 2 cups (500ml) full fat milk
  • 1/2 tsp nutmeg (grated)
  • salt and pepper (to season)
  • 1 tbsp parmesan (grated (optional))
  • 2.8 oz (80g) gruyere cheese (grated (optional))

Instruction

  • Add the olive oil to a saucepan and warm it for a couple of seconds before adding the flour.
  • Once the flour has been added mix it together with a whisk or wooden spoon to form a paste and let it cook for one minute (this cooks the flour so you don't have a floury taste in your sauce).
  • Add 1/4 of the milk and whisk constantly to remove any lumps. Once it has started to thicken add a little more milk (around 1/4 at a time) until you have used up all the milk.
  • Continue to heat the sauce whilst stirring until thick. Once it's thick enough to coat the back of a metal spoon, take it off the heat and add nutmeg, salt and pepper and cheese if making a cheese sauce.
  • If making a cheese sauce stir the sauce until the cheese has melted. You may need to put it back on the heat for a few seconds. If it thickens too much add another splash of milk.
