To create the chocolate drip, drop tablespoons of the melted chocolate around the edge of the cake. Using the back of the spoon gently push some of the chocolate over the edge of the cake to allow the drips to run. You can push more (or less) of the chocolate over the edge to create uneven lengths of drip. Continue until you have gone around the perimeter of the cake. Spoon the remaining melted chocolate into the middle of the uncovered cake and spread it out evenly on the top. Allow the chocolate glaze to set in a cool place. If necessary, put it in the fridge to allow it to set. Decorate the top with white chocolate bark, brushed with a little gold dust if wished. Altertively decorate as wished.
