When preparing the short pastry knead in the bitter almond aroma. Grind 50 g pistachios finely. Separate the egg. Knead egg white, raw marzipan paste and ground pistachios with the dough hooks of the hand mixer to a smooth mixture.
Roll out the dough on a floured work surface until it is about 3 mm thin and cut out circles (about 6 cm Ø). Spread on 1-2 baking trays lined with baking paper. Using two teaspoons, place a small teaspoon of filling in the middle of each cookie.
Flip up three sides and press them together with your fingers to form a tricorn. Cut the cherries into eighths and decorate half of the hats with them. Decorate the remaining cones with the remaining pistachios.
Spread the dough with whisked egg yolk. Bake in the preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: stage 2) for 12-14 minutes. Let cool on a cake rack.
