Mix together the
butter and ginger biscuits crumbs, then pack around
the sides and base of an 18cm/7in loose-based flan
tin. Chill in the fridge while making the filling.
Put the cake
crumbs into a large bowl, with the orange juice and
leave to soak. Warm the dates thoroughly, then mash
and blend into the cake crumbs along with the nuts.
Melt the
chocolate with 45-60ml/3-4 tbsp of the ream. Softly
whip the rest of the cream, then fold in the melted
chocolate mixture.
Stir the cream
and chocolate mixture into the crumbs and mix well.
Pour into the biscuits case, mark into portions and
leave to set. Scatter over the grated chocolate and
dist with icing sugar. Serve cut in wedges.
