Mix flour, sugar, spices, baking powder, salt and vanillin sugar in a bowl. Add butter in pieces and eggs. Mix first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Knead in the cranberries and pistachios. Quarter the dough, form each piece into a roll of about 15 cm
Place the rolls on a baking tray lined with baking paper, keeping a distance between them. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 15 minutes. Let them cool down
Cut the rolls diagonally into thin slices. Place the cut surface on 3 baking trays lined with baking paper. Roast the baking trays one after the other in the oven at the same temperature for 8-10 minutes until golden brown. Allow to cool down
Waiting time approx. 1 hour
