Stir pudding powder, 3 tablespoons of milk, amaretto and sugar until smooth. Bring the remaining milk to the boil, stir in the pudding powder and bring to the boil again briefly. Place in a bowl to cool down. Separate puff pastry sheets and defrost at room temperature in 20-30 minutes. Drain the peaches.
Separate egg, mix egg yolk and cream. Stir quark into the pudding. Roll out puff pastry sheets, one by one to rectangles (approx. 12 x 24 cm) on a floured work surface. Place a heaped tablespoon of pudding on each half. Place a half peach and an amaretti on top. Brush the edges with egg white and fold the free halves over the peaches. Press well all around with a fork. Place on a baking tray lined with baking paper, brush with egg yolk and sprinkle with flaked almonds and decorating sugar. Let the particles rest for about 10 minutes. Bake in a preheated oven (electric: 200 °C / gas: level 3) for 15-20 minutes.
