Start this recipe by making the dough. Place all the ingredients in a food processor or mixer and mix to dough with enough of the warm milk. Allow to knead for a minute in the mixer or processor then remove and place into a clean bowl. Cover with cling film and allow proving for 30-40 minutes. Meanwhile, make the cranberry jam. Place the cranberries, sugar, orange juice and zest and add in ½ cup of water. Bring to the boil and cook down for 15 minutes until the cranberries pop and the jam thickens. Add in the corn flour, bring to the boil and take off the heat. Allow to cool down while you wait for the dough to prove. When the dough is ready, knock back and roll out on a floured surface to a large rectangle. Brush all over with ½ of the melted butter and spread over the cooked cranberry jam. Sprinkle over the sugar, cinnamon and chopped walnuts. Roll up tightly and cut up into 14 slices. Grease a large round baking tray and lay on the dough slices in the shape of a ring overlapping the slices slightly. Brush again with the remaining butter and allow proving again for 30-40 minutes or doubling in size. When ready, cook in the oven at 200`c for 35-40 minutes or until golden brown and cooked through. Serve this recipe sliced whilst still warm or cold.
