White Sauce


  • 27 g butter
  • 27 g (3 tbsp) flour
  • 1/2 tsp mustard powder (optional)
  • 310 ml (1 1/4 cup) milk


  • Melt the butter in a pan and add the flour and mustard powder (optional) then stir, with a wooden spoon, to form a paste.
  • Over a gentle heat add half a cup of the milk and continually whisk to prevent any lumps forming. Slowly add another half cup of milk and continue to whisk.
  • Repeat until all the milk is used up and continue to whisk until sauce has thickened.
