i made this for the first time at halloween and it was the first time ever i have had people asking me for recipe! I didnt use Nigella's recipe but one from a magazine which virtually the same apart from it recommended a couple of bars of chopped frys turkish delight bars. I didnt have any so missed it out. Have since made it again and added glace cherries as well as biscuit and mallow. Have made it with rich tea and digestives and not much difference, have also seen a recipe suggesting you use shortbread whihc would be nice. I dont dust with icing sugar (dont think its necessary and cant be bothered!)
