Defrost the raspberries and defrost 8 beautiful berries lying next to each other for decoration.
Mash the remaining raspberries with a hand blender and pass through a fine sieve. Stir in icing sugar and quark.
Pour the raspberry cream into a piping bag with a large star-shaped spout and squirt it onto the meringue shells. Dribble chocolate sauce over the tartlets, decorate with raspberries and serve.
