Chopping chocolate. Warm the cream and melt the chocolate in it while stirring (must not boil). Place the chocolate cream in a mixing bowl and refrigerate for about 3 hours. In the meantime, whisk fat, sugar, salt and vanilla sugar with the whisk of the hand mixer until foamy, gradually add eggs. Mix flour and baking powder, sieve onto the fatty egg mixture, add orange fruit and milk and mix.
Pour the dough into greased tartlet cups (50 ml content) sprinkled with breadcrumbs and bake in the preheated oven (electric oven: 200 °C / gas: level 3) for approx. 20 minutes. Remove the tartlets from the oven, let them cool down a bit, turn them out of the baking tins, prick them several times with a wooden skewer and sprinkle them with orange juice. Dust the cakelets with icing sugar. Whip the chocolate cream with the whisks of the hand mixer, fill into a piping bag with a star-shaped spout and squirt one tuff onto each cakelet. Serve decorated as desired with orange peel, mint and mandarins
