Sift 250 g icing sugar finely. Beat the egg whites until stiff, adding 1 pinch of salt and the icing sugar. Take off approx. 5 tbsp. of the egg whites to coat the snowflakes later and put them in a cool place.
Mix almonds, cardamom, ginger, cloves and cinnamon and add to the remaining egg whites with vanilla pulp. Knead with the dough hooks of the mixer to a smooth dough.
Preheat the oven (electric cooker: 150 °C/circulating air: 130 °C/gas: see manufacturer) and line two baking trays with baking paper. Dust two large pieces of cling film (each approx. 30 x 45 cm) thinly with icing sugar. Roll out the almond paste between the sheets 0.5-1 cm thick. Cut out snowflakes (approx. 8 cm Ø each), knead the rest of the dough again briefly, roll out and cut out.
Spread the snowflakes on the baking trays and brush them with the cold egg whites. Bake in the hot oven for about 15 minutes, one sheet at a time. Let cool down briefly. Carefully remove from the paper and let it cool down on a cake rack.
