Servings

Ingredients for 2

  • 4 slices thick brioche loaf
  • 120 g dry-cured ham , such as jambon de Paris
  • 150 g Gruyere , grated
  • 2 tsp Dijon mustard
  • sea salt and white pepper , to taste
  • For the mornay
  • 30 g butter
  • 30 g plain flour
  • 300 ml whole milk , warmed
  • 1 pinch grated nutmeg
  • 1 egg yolk

Method

  1. Make a roux with the butter and flour, then whisk in the warm milk to a smooth sauce. Simmer 2 minutes, season with nutmeg, salt and white pepper.
  2. Off the heat, beat in the egg yolk and two thirds of the Gruyere to finish the mornay.
  3. Lightly toast the brioche, spread two slices with Dijon, then layer the ham and a little mornay and close the sandwiches.
  4. Spoon a generous layer of mornay over each top and sprinkle with the remaining Gruyere.
  5. Grill for 4-5 minutes until deeply golden and blistered.
  6. Rest for a minute so the sauce sets slightly, then serve with a green salad.
