Finely chop the chocolate for the pudding. Bring milk and cream to the boil in a small pot and remove from the heat.
Puree the chocolate, 1 pinch of salt and egg with a hand blender for about 2 minutes. Add peanut butter. Puree for another 2 minutes. Add the cream-milk-mix and puree for another 2-3 minutes until a smooth cream is obtained.
Pour cream into four small bowls and chill for about 15 minutes.
For the fruit salad, peel the orange so that the white skin is completely removed. Remove the fillets with a sharp knife between the parting skins. Squeeze the juice out of the parting skins and collect it.
Cut the fillets a little smaller. Remove the physalis from the casings, wash and cut in half. Mix orange juice, vanilla sugar and cognac. Mix with the fruit. Arrange chocolate-peanut pudding with fruit salad.
