Preheat your oven to 325°F (165°C).
In a saucepan, heat the cream with the vanilla bean.
Warm it until it almost boils, then remove from heat.
Let it sit for 15 minutes to soak in the flavor.
Whisk the egg yolks and sugar in a bowl.
Keep whisking until the mixture looks smooth and pale.
Take out the vanilla bean from the warm cream.
Slowly pour the cream into the egg mixture while whisking.
Strain the mixture to remove any lumps.
Pour it carefully into the ramekins.
Place the ramekins in a deep baking dish.
Pour hot water into the dish until halfway up the ramekins.
Bake for 40-45 minutes until the custard is just set.
It should still jiggle a bit in the center.
Cool them, then chill in the fridge for at least 2 hours.
Sprinkle the tops with the remaining sugar.
Use a kitchen torch to melt the sugar until golden.
Let the sugar bubble and harden into a sweet crust.
