Place puff pastry sheets next to each other and defrost at room temperature for about 20 minutes. Place 3 plates on top of each other. Roll out to two squares (each approx. 30x30 cm) and leave to rest in a cool place for approx. 15 minutes.
Cut out 2 circles (each 28 cm Ø) from the squares and place them on two baking trays lined with baking paper. Mix the egg yolks and 1 teaspoon of cream. Spread one base with it and sprinkle with almonds and sugar crystals.
Bake the sprinkled base in a preheated oven (electric: 200 °C/ gas: level 3) for 13-15 minutes. Bake the rest of the base in the same way. Cut the sprinkled cake into 12 cake pieces while still warm and let cool.
Roughly chop the chocolate and melt in a hot water bath. Spread the whole pastry base with chocolate and let it dry. Drain the cherries and collect the juice. Put 12 cherries aside for decorating.
Stir cornflour and 6 tablespoons of juice until smooth. Boil up the rest of the juice, 2 tablespoons of sugar and lemon zest. Remove lemon zest, stir in cornflour and bring to the boil again. Fold in the cherries, let the compote cool down a little and spread it on the chocolate pastry base until smooth.
Let it cool down. Whip the rest of the cream, sugar, vanillin sugar and cream setting agent until stiff. Put 1/4 of the cream into a piping bag with a star-shaped spout. Spread the remaining vanilla cream loosely on the cherry layer and squirt 12 cream tuffs at even intervals.
Decorate the tuffs with one cherry each. Heat the jelly and sprinkle the cherries with it. Put the cake in a cool place. Dust the puff pastry wings with icing sugar and place them diagonally on each tuff just before serving.
Serve decorated with mint. Makes about 12 pieces.
