Chocolate nut clusters
Place the cream in a saucepan and bring to the boil. Grate half of the chocolate into a mixing bowl and pour the cream over it. Mix thoroughly and stir in half of the crushed hazelnuts. Allow to cool, then with hands dusted with icing sugar, scoop a rounded teaspoon of the set mixture out and roll into a ball. Place on a plate and continue until all of the mixture is used. Chill for 1 hr. Place the remaining crushed hazelnuts on a large plate and have an extra plate handy. Break up the remaining chocolate into a heat-proof bowl. Place the bowl over a pan of gently simmering water, taking care not to let the bowl touch the water. Stir occasionally until melted. Remove from the heat and stir until smooth, then dip each ball into the chocolate, to cover completely, using two teaspoons. Place on the plate of nuts and roll around to cover. Transfer to the extra plate. Repeat with all the balls. Chill for 1 hr, then serve.
