Lightly flour a work surface and tip the risen dough out onto it. Lightly flour the dough and roll it out into a 15 x 26 inch (35 x 65cm) rectangle. Spread half of the melted butter over the surface of the dough. Evenly sprinkle on half of the spiced sugar and press it into the dough by rolling it over it gently. Fold the dough into thirds like a business letter. (see bottom of post for a .gif to explain).
Roll this out again into a 15 x 26 inch (35 x 65cm) rectangle. Spread the remaining butter over the surface, evenly sprinkle on the remaining spiced sugar and all of the mixed dried fruit. Starting at the short edge of the rectangle, roll the dough up tightly into a log.
Cut the dough into 12 even pieces. Place cut side-up into an oiled 9x13-inch baking tin. Cover with a clean tea towel and leave somewhere warm for 30 minutes to almost double in volume.
Meanwhile preheat the oven to 180oC (350oF).
Once risen, bake the rolls for 20-25 minutes until golden brown around the edges. Leave to cool.
