Mix together the
chocolate and hazelnut spread and 75ml/5 tbsp of the
double cream in a bowl.
Place the
remaining cream in a second bowl, sift in the icing
sugar and beat until softly whipped.
Lightly fold in
the chocolate and hazelnut mixture with the chopped
chocolate until the mixture is rippled. Transfer to
a plastic freezer container and freeze for 3-4
hours, until firm.
Remove the ice
cream from the freezer about 10 minutes before
serving to allow it to soften slightly. Spoon or
scoop into desert dishes or glasses and top each
serving with a few plain chocolate curls.
