For the tartlet case:

For the Béchamel sauce:
1 Melt the butter in a saucepan over a low heat. Add the flour and cook out for 10 mins. Be careful not to burn it. 2 Gradually add the milk in small stages – 40-50ml at a time. Allow to cook over a low heat for 10 mins until the mix doesn’t taste of flour anymore.
3 Add the mustard and cheese and blend with a stick blender. Set aside.
