Melt the chocolate in a warm water bath. Separate the eggs. Mix the egg yolks with 125 g icing sugar until creamy. Fold the chocolate into the egg yolk mixture. Beat the egg white with 1 pinch of salt until stiff and fold in.
Line the bottom of a springform pan (26 cm Ø) with baking paper. Pour in the mixture and smooth it down. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: not suitable/ gas: level 2) for approx. 35 minutes. Let the base cool down and remove from the springform pan. Place on a cake plate and sprinkle with rum. Mix cranberry compote and spread on top. Whip the cream until stiff, sprinkle with vanilla sugar. Pour into a piping bag with a star-shaped spout and squirt strips onto the cake. Knead marzipan with 25 g icing sugar. Roll out marzipan between two layers of baking paper to the size of the springform pan.
