These eggs are cooked in little ramekins (en bain marie), or as we know it in English, a water bath.
1 Set your oven to medium.
2 Break an egg per person into each ramekin, add a teaspoon of butter and a tablespoon of cream.
3 Finely grate some parmesan cheese over the mix. You could also add a piece of smoked salmon or some asparagus tips
4 Sit the dishes in a baking tray, carefully pour in boiling water to come ½ way up the height of the ramekin.
