Put some hot water in a gratin dish, roaster, etc. and place in the oven.
Butter 4 molds and break 2 eggs into each mold.
Sprinkle the eggs with the chives, salt, pepper and carefully pour the cream over the eggs and finally sprinkle with the cheese.
Put the molds in the water bath, should be about halfway in the hot water.
Cook for 10 minutes: the egg white should be set, the egg yolk should still be liquid (test: shake it lightly), leave in for 1-2 minutes longer, if you like, serve immediately in the mold.
It's actually a starter, I prefer it (in contrast to the "real Parisians") for breakfast.
