Cut the vanilla pod in half lengthwise and scrape out the pulp with the back of a knife. Bring the double cream, cream, vanilla pulp and scraped pod to the boil. Mix 30 g sugar and egg yolks with the whisk of the hand mixer until the mixture is thick and almost white. Stir 4 tablespoons of the cream mixture into the egg mixture and slowly stir in the rest of the boiling cream. Stir constantly until the cream is thick and almost white.
Remove the vanilla pod and pour the cream into 4 small glasses and chill for about 2 hours. Defrost the raspberries. Puree the raspberries with 2 tablespoons of sugar and pass through a sieve. Add the raspberry puree to the cream just before serving
