Wash and peel the pears. Cut out the flower. Boil 1 litre of water, 50 g sugar and lemon juice. Add the pears and let them simmer for about 5 minutes. In the meantime, place the puff pastry slices next to each other and let them thaw at room temperature for about 15 minutes. Carefully lift the pears out of the lemon water with a skimmer, drain well and allow to cool.
Separate the egg. Roll out each puff pastry slice rectangularly (approx. 10 x 20 cm) on a floured work surface. Brush the edges with egg white. Place one pear on each puff pastry slice, fold in, press together firmly at the top. Place pears on a baking tray lined with baking paper. Whisk the egg yolks with 2 tablespoons of milk. Spread the puff pastry with it. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 25 minutes. Coarsely grate the marzipan. Bring 450 ml milk to the boil, stir in marzipan and dissolve in it. Stir 50 ml milk, sauce powder and 2 tablespoons of sugar until smooth and stir into the boiling milk. Bring to the boil and simmer for about 1 minute while stirring.
