Take the puff pastry out of the fridge and let it rest in the package for about 10 minutes. For the filling, briefly roast the almonds in a pan without fat while turning. Coarsely grate the marzipan. Mix plum puree, almonds and marzipan. Roll out the puff pastry.
Spread the filling evenly over the pastry, leaving a 5 cm margin. Roll up the dough from the long side. Press the ends together. Place on a baking tray lined with baking paper. Whisk egg yolk and milk. Spread the dough with egg mixture. Cut the dough roll diagonally to the middle at a distance of about 10 cm. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 50 minutes. Mix icing sugar and 2-3 tablespoons of water.
