Croque Madame  

Ingredients
Bread (I like sourdough but any will work)
60g of ham per sandwich (I used prosciutto, leg ham works well)
1 fried egg per sandwich
300g Comte cheese
1 teaspoon of mustard per sandwich and 1 tbsp for the sauce
120g butter
2 heaped tbsp flour
200ml milk
Salt to taste
Chives to garnish
Method
1. Start by buttering one side of each piece of bread with melted butter and grill on a hot pan or under the grill.
2. Spread the mustard on 1/2 of the bread, then place the ham and some of the grated cheese (saving at least half the cheese for the mornay sauce).
3. Place the second piece of bread on top of the cheese and onto an oven-safe tray.
4. To make the mornay sauce, add flour to the leftover butter and whisk until it turns golden brown.
5. Slowly add the cold milk and whisk until smooth.
6. Add the rest of the grated cheese and whisk until smooth and silky.
7. Take it off the heat, add the mustard, season with salt and stir well.
8. Pour the finished mornay sauce over the sandwiches and place in a 200°c oven for 15-20 minutes or until they go a lovely brown colour.
9. While the sandwiches are in the oven, fry some eggs.
10. Serve each sandwich with a fried egg on top and garnish with chopped chives.
11. Enjoy!
