Break the chocolate into small pieces. Mix the fine cornstarch with cocoa and 1/4 l milk well. Bring the rest of the milk to the boil with the sugar, the vanilla pulp and the sliced pod, salt and chocolate. Add the mixed cornstarch and cook briefly while stirring constantly. Take out the vanilla pod.
Pour the mixture into a cold-rinsed dish or 4 to 6 molds and allow to cool. Only then fall. Garnish with whipped cream and grated chocolate.
Tip: To refine, a shot of brandy or orange liqueur can be added to the boiling milk.
