How to Create the Dish

Preheat the oven to 180C/350F/Gas 4.

Butter the bread, spread with half the mustard and make four ham sandwiches.

Using a large circular cutter, cut each sandwich into a circle (if you don’t have a cutter, remove the crusts and cut the sandwiches into triangles). Place in a small oval ovenproof dish and pour a little ale over each sandwich, if using.

In a pan, bring the cream up to the boil. When it starts to thicken, remove from the heat. Stir in the remaining mustard, the Worcestershire sauce, egg yolks and 225g/8oz of the cheese. Season with salt and pepper.

Pour the sauce over the sandwiches and scatter the remaining cheese over the top.

Bake for 12 minutes, or until golden-brown and bubbling. Serve with dressed salad leaves.
