Sift 250 g icing sugar. Beat the egg whites until stiff, stirring in icing sugar by the spoonful. Knead the hazelnuts, vanilla sugar and cinnamon with the beaten egg whites
Knead the hazelnut mixture into a dumpling on a work surface dusted with icing sugar and roll out between 2 layers of foil approx. 8 mm thick. Cut out shooting stars (approx. 3.5 x 8 cm), dipping the cutters in warm water from time to time. Knead the rest and cut out further
Place stars on 2 baking trays lined with baking paper. Bake one after the other in a preheated oven (electric oven: 150 °C/ convection oven: not suitable/ gas: stage) for 15-20 minutes and let cool off. Sift 125 g icing sugar and mix with egg liqueur to a smooth glaze. If the icing is not yellow enough, add a little food colouring. Spread the stars with it, let it dry and pack it in an airtight tin
Waiting time approx. 1 hour
