- 80 g butter
- 20 g (2 T) flour
- 190 ml (¾ cup) milk
- 5 ml (1t) Dijon mustard
- 1 free-range egg yolk
- nutmeg, grated, for seasoning
- sea salt and freshly ground black pepper, for seasoning
- 8 slices white bread
- 4 slices ham
- 140 g Gruyère cheese, grated
Melt the butter in a saucepan, then add the flour and stir until the well combined.
Pour in the milk then add the mustard. Whisk until smooth then simmer for 3 minutes.
Whisk in the egg yolk and season with nutmeg, salt and pepper.
Place 4 slices of bread on a baking tray, each topped with a slice of ham*.
Pour over the béchamel sauce and distribute the Gruyère cheese among the four slices, then top with the remaining slices of bread.
Heat a little butter in a frying pan and fry each sandwich on both sides until golden brown, adding more butter as required.
Slice each sandwich diagonally in half and serve immediately.
*Cook's tip: Woolworths sells a delicious range of Halaal cold meats, including tongue and pressed beef, that can easily subsitute the ham in this recipe
