Place paper cuffs in 8 muffin tins and chill. In the meantime, chop dark chocolate coarsely and melt it on a warm water bath. Spread the inside of the paper cuffs with melted chocolate and refrigerate again.
Soak the gelatine. Coarsely crush the pink berries. Heat mascarpone and double cream in a pot (do not boil!). Coarsely chop white chocolate and melt in it. Remove from heat and fold in pink berries.
Let it cool down until the cream has reached room temperature. Pour into the chocolate moulds and immediately refrigerate again for 2 hours. Shortly before serving, remove paper cuffs from the chocolate.
Raspberry sauce tastes good with it.
