For black and white pastry, cut the dough in half. Knead one half with cocoa. Roll out both doughs one after the other about 3 mm thick. Cut out 55 biscuits with a triangular cutter (5-6 cm side length). Put them on 2-3 baking trays lined with baking paper. Stir egg yolk and cream until smooth. Brush light-coloured triangles with them.
Spread dark pastry with milk. Bake the trays one after the other in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for about 10 minutes. Let cool on a cake rack. Place a small spot of the nougat cream on each of the dark cookies. Add light triangles in staggered order. Place another dab of nougat in the middle of the light biscuits. Decorate with pine nuts
Waiting time approx. 30 minutes
