Mix butter and sugar. Mix flour and salt. Knead orange zest and flour into the butter. Chill for 30 minutes. Roll out dough about 8 mm thick and cut into strips (about 7 x 2 cm).
Put them on 2-3 baking trays lined with baking paper at a distance of 3 cm and make holes in the biscuits with a wooden stick. Bake the trays one after the other in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for about 15 minutes. Take out the biscuits and pierce the holes. Let the biscuits cool down. Melt the chocolate coating over a warm water bath and decorate the biscuits
Waiting time approx. 45 minutes
