Mix the first 4 ingredients by hand and make a dough. Then add the candied peel and cinnamon and mix again, shape into a ball and let it rest for 30 minutes in the fridge. Roll into a long strip, and taking a little bit of dough at time shape with your hands into walnut size biscuits. Place the biscuits onto a baking tray lined with baking paper. Bake at 160˚C for 10-12 minutes. Let the biscuits cool down and then decorate: For half of the biscuits I just dipped one end in melted dark chocolate and sprinkled with some sugar granules (which I got from Italy) on top. For the rest I rolled some ready made white icing, cut it into small circles, to top each biscuit (spread a little apricot jam first to secure the icing in place) and then I decorated them with green and red icing pens.
