Divide the dough into 4 equal pieces and then take a little piece, around 50 grams, off each piece of dough. You will have four big pieces of dough and 4 little pieces of dough.
Shape each of the large pieces into tight balls and place them on a baking tray you have lined with non stick baking parchment.
Divide the each of the 4 small pieces into 5 REALLY small pieces. So now you have 20 REALLY small pieces of dough.
Roll 4 of the REALLY small pieces of dough into small balls and set them aside on a baking tray covered with non stick parchment. These are your "skulls". Roll the remaining 16 REALLY small pieces into long, thin, "sausages". These are your "bones". As you roll these, space out your fingers as you roll so that you have thicker bits and thinner bits. Each "sausage" reach from the middle to the bottom of the larger dough balls. When you have rolled these, set them aside with the little balls.
Beat up your glaze/glue and bush this generously over the big balls of dough. Stick the small balls "skulls" on the top in the centre of each big ball and then stick the "bones" on, draping them down the sides. The photo has 5 bones (I realise that now!) but don't worry about it. Four is sufficient!
Cover these with a light cloth and let them rest for 1-2 hours until they have doubled in size.
When the dough has risen, preheat the oven to 220 degrees celcius.
Bake for 20 minutes. Tap the bottoms: they will sound hollow when they are done. Remove them from the oven and place them on a wire rack.
While they are still warm, brush them with melted butter and then sprinkle them generously with sugar. You will want to do this over a tray of some kind so the sugar does not go all over the floor. Then, place them back on a rack to cool.
Eat! Yum! You can share this bread with both the living and the dead. If you want to be EVEN MORE indulgent, you can slice these and spread clotted cream or "nata" on the slices before eating them.
