Roughly chop the chocolate. Bring milk, cream and 100 g sugar to the boil and remove from the heat. Add the chocolate pieces and rum to the hot milk-cream mixture and melt while stirring. Mix egg yolks and 5 tablespoons of chocolate cream, then stir into the remaining milk. Stir the chocolate milk in a bowl over a hot water bath to a creamy - slightly thick consistency (peel to a rose) and then pass through a fine sieve.
Pour the chocolate cream into 6 deep plates or cups and cook in a preheated oven (electric cooker: 100 °C/ convection oven: 75 °C/ gas: not suitable) for approx. 1 1/2 hours. Then put in a cool place for 2 hours. In the meantime, remove thin strips from 1 orange with a pestle ripper. Let them simmer with orange liqueur at medium heat for about 15 minutes. Peel all oranges so that the white skin is completely removed. Remove the fillets with a sharp knife between the parting skins. Cut the vanilla pod in half lengthwise, scrape out the pulp with the back of a knife. Caramelise 50 g sugar light brown, fill up with orange juice, add spices and boil down by half. Stir the starch and 2 tablespoons of cold water until smooth and thicken the orange and spice stock with it. Allow to cool a little and add the orange fillets and orange zests, then chill.
