Preheat oven to 200C and grease the baking tin with butter
Soak the fruit for at least 2 hours (better overnight) with the brandy or other booze so it's plumped up ready to use
Melt the butter in a small pan
Cut the filo pastry to fit your baking tin and lay the first sheet on bottom of baking tin and paint with the melted butter, do this for another 5 sheets
sprinkle the walnuts and fruit mixture over the pastry and add all the orange zest and the demerara sugar
Lay another sheet of filo pastry on top and paint with the melted butter and carry on till all sheets used then paint the top with remaining butter
use a sharp knife to cut the pastry into pieces (I made 6 slices)
Bake for approximately 30 minutes till golden on top
leave to cool in the tin while you make the syrup
make the orange juice up to 150ml with water and pour into small pan with the sugar and cinnamon
heat gently till sugar dissolved then boil and simmer about 10 minutes to make a spiced syrup
pour syrup over the baklava and dust with icing sugar just before serving
