Cut the Siúcra Roll Out Icing into very small cubes. Place in a saucepan and pour the cream over. Heat over a very low heat until the Siúcra Roll Out Icing has completely melted, stirring constantly.
Remove the chocolate mixture from the heat. Cut the butter into cubes and stir into the chocolate mixture until completely melted. Stir the cream into the chocolate mixture until just combined. Don't over whisk or the truffle mixture will split. Pour into a shallow container that is lined with baking paper, cover and place in the fridge overnight to set.
Once set, place on a chopping board and cut into 36 equal pieces. Place the Siúcra Instant Royal Icing in a bowl with two teaspoons of water and stir until the icing is a runny consistency. If it is a little too thick, add some more water. Drizzle the icing over each chocolate truffle. The chocolate truffles can also be dipped in melted chocolate and then rolled in cocoa powder, coconut, nuts or grated chocolate.
