Step by step recipe:

1. 5 min.

   Fry the ham

   
   Heat 1 tablespoon oil in a frying pan on high heat.
   
   When really hot, fry the slices of ham on both sides, in batches if necessary.
2. 

   Dip the bread

   
   Prepare the slices of bread by removing the crust, if you prefer, then lay them out in pairs, so that you have top and bottom slices side by side.
3. 2 min.
   Mix 2 eggs and 30 ml liquid cream, salt and pepper with a whisk.
4. 1 min.
   Pour the beaten egg-cream mixture into a plate or shallow dish.
5. 2 min.
   Dip the bottom slice briefly into the mixture...
6. 2 min.
   ... then lay it dipped side downwards.
   
   Place a slice of ham and your chosen cheese on top.
7. 7 min.
   Dip another slice into the egg-cream mixture and lay on top of the croque, dipped side upwards.
   
   Make all the croque sandwiches like this, lying them on a baking sheet or chopping board as you go.
8. 6 min.

   Fry the croque-monsieur

   
   Pour 4 tablespoons oil into the same frying pan as you used for the ham, on medium heat.
