Separate the egg. Cut butter into small pieces. Mix butter, sugar, flour, egg yolk, aniseed and flavouring to a smooth short pastry. Cover and chill for about 30 minutes. Then roll out, preferably in 2 portions, to a thickness of approx. 5 mm on a lightly floured work surface.
Cut out small shooting stars (approx. 6 cm long) and stars (approx. 5 cm Ø). Place on 1-2 baking trays lined with baking paper. Knead the dough again and again until smooth and roll out again. Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 8-10 minutes, allow to cool. Beat egg white and icing sugar until stiff. Add lemon juice carefully. Colour half the icing yellow. Pour 1 heaped tablespoon each of white and yellow icing into a piping bag with a very small hole. If necessary, dilute the rest of the mixture with a little lemon juice.
