1. Cut the vanilla bean lengthwise, then put all the ingredients, EXCEPT the heavy cream, in the bowl and cook for 12 minutes at 90°C, speed 3.
When the timer goes off, let it cool slightly, then add the 2 tablespoons of heavy cream and mix for 10 seconds at speed 3.
Pour the cream into a container and stir it regularly with a spoon for the first half hour to prevent a "skin" from forming on top, then pour it into individual small pots and let it cool at room temperature and then in the refrigerator to thicken!
Best enjoyed the next day, when the creams are well chilled.
