Mix flour, icing sugar and salt. Add egg and butter in flakes. Knead first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Cover and chill for about 1 hour. For the filling, roast the pine nuts in a pan without fat, remove and let them cool down. Put approx. 2 tablespoons aside for decorating.
Finely chop the remaining pine nuts. Mix with 100 g jam and Campari. Roll out the dough on a floured work surface. Roll out squares (approx. 4.5 x 4.5 cm). Whisk egg yolk with milk. Spread half of the dough squares with part of the egg yolk milk. Place a teaspoon of filling in the middle. Place the rest of the squares on top and press down well at the edges. Place on a baking tray lined with baking paper. Brush with the rest of the egg yolk. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 15-20 minutes. Let cool on a cake rack.
