  • 1 tsp Dijon mustard

Dijon mayonnaise

Method

1
Begin by making a thick béchamel sauce. Melt the butter in a saucepan and stir in the flour. Cook and stir for a minute or so to cook out the floury taste, then stir in the milk bit by bit, ensuring any lumps are whisked out before adding more milk
2
Once all the milk has been added and you have a smooth, thick sauce, stir in the Dijon mustard then taste and add nutmeg and salt until you're happy with the flavour. Remove from the heat and set aside
3
Make the Dijon mustard by stirring the mustard and mayonnaise together. Set aside
4
Now it is time to assemble the sandwiches. Begin with a layer of Dijon mayonnaise, followed by a slice of ham and then slices of Gruyère cheese. Close the sandwich and spread the top of the lid with some béchamel sauce
5
Place the sandwiches on a tray and under the grill for a few minutes until the béchamel has started to colour and the cheese is nice and melted
6
Serve immediately with an extra dab of Dijon mayonnaise on the side
