For the crème brûlée, cut open the vanilla bean and remove the pulp.
Mix the sugar, egg yolks and vanilla pulp in a bowl. Bring the whipping cream to the boil in a saucepan and gradually stir into the sugar mixture.
Pour the mixture through a sieve into ovenproof molds. Poach the crème brûlée at 180 °C in a bain-marie for about half an hour.
Sprinkle the crème brûlée with sugar and caramelize under the grill grate.
