Heat oven to 200C/180C fan/ gas 6 and butter 4 small (about 200ml) ramekins. Sprinkle the Parmesan into the ramekins, turning until all sides are covered. Place the milk and bay leaves in a large saucepan over a gentle heat and bring to the boil. Turn off the heat and leave to infuse for 15 mins.

Discard the bay leaves, add the butter and flour, and return to a low heat. Very gently simmer, stirring continuously with a balloon whisk, for about 6 mins until you get a smooth, thick white sauce. Make sure that you get right into the corners of the pan to stop the sauce from catching or becoming lumpy.
