150g butter

3 tbsp cake flour

1 tbsp corn flour

1 tsp salt

1 tsp fine black pepper 

½ tsp nutmeg

1 tbsp mustard powder

1½ litre of warm to hot milk

1 cup of grated cheese if you are making a cheese sauce.


Add butter to a medium-sized pot and allow to melt on medium to high heat.

Now add the flour, corn flour mixed with half a cup of warm milk, salt and spices and stir into butter with a hand whisk for a minute or two to allow the flour to cook through. 

Add milk a cup at a time, stirring with your whisk until the sauce thickens.

Repeat this process while adding the warm milk and stirring continuously until all the milk has been used and your sauce is silky and a bit thick. 

For cheese sauce add your grated cheese at this point and stir until all cheese has melted.
