2 Roll the dough into 2 sausage shapes, about the width of a ยฃ2 coin (1 and a 1/2 inches). Wrap in clingfilm and leave in the fridge overnight.
3 Using a sharp knife, cut the dough into 4mm thick discs and lay on a baking tray lined with parchment and bake in pre-heated oven, 135C-150C/Gas Mark 1-2 for 45 minutes, or until they start turning golden at the edges.
