Mix 250 g almonds and icing sugar and grind very finely in the universal chopper. Mix cocoa, spices, vanilla sugar and kirsch and add to the almond-sugar-mixture. Beat the egg whites until stiff and gradually add them to the almond mixture until you have a malleable dough (you may not use all the egg whites). Chill for 1 hour. Sprinkle the work surface with sugar and roll out the dough in portions about 8 mm thick.
Cut out about 40 biscuits with a flower cutter (approx. 4/6 cm Ø). Put the rest of the almonds, brown and white sugar on 3 plates and press the cookies with the upper side into the almonds or into brown or white sugar as desired. Put them on 2 baking trays lined with baking paper. Bake one after the other in a preheated oven (electric: 150 °C/ gas: level 1) for 12-15 minutes. Place on a cake rack and allow to cool
Waiting time approx. 1 hour
