Cut the vanilla pod lengthwise and scrape out the pulp with a knife. Put vanilla pulp, whipped cream, milk and icing sugar in a pot and bring to the boil while stirring, then let it cool down and put it in a cool place for about 45 minutes
Mix the cooled cream-milk mixture with the egg yolks. Then pour the mixture into 4 flat ovenproof moulds (approx. 130 ml content). Place the ramekins on the fat pan of the oven, add hot water so that about 2/3 of the ramekins are in the water. Put the crème brûlée in a preheated oven (electric range: 125 °C/ convection oven: 100 °C/ gas: level 1/2) and let it set for 50-60 minutes.
Take the ramekins out of the oven and off the fat pan, let them cool down and put them in a cool place for several hours, preferably overnight
Sprinkle 1-1 1⁄2 tablespoons of brown sugar on each crème brûlée and caramelise with a crème brûlée distiller until golden brown. Serve with an espresso
waiting time approx. 13 hours
