Preparation: Roast the hazelnuts briefly in a pan without fat, take them out and let them cool down. Sift icing sugar. Beat egg white and lemon juice until stiff. Gradually add the icing sugar while stirring. Remove 1/3 of the beaten egg white and fill into a freezer bag, close the bag. Mix cinnamon, lemon peel, nuts and almonds and stir into the remaining beaten egg white.
Roll out the dough on a work surface dusted with icing sugar to a thickness of about 1/2 cm. Cut out stars about 5 cm in size, dipping the cutter in flour in between. Knead the remaining dough again and again. Put the stars on three baking trays covered with baking paper. Cut off a corner of the freezer bag, sprinkle beaten egg white on the stars and smooth them down with a knife (moisten the blade again and again). Bake the trays one after the other in a preheated oven (electric cooker: 150 °C/ convection oven: 125 °C/ gas: level 1) for approx. 15 minutes
