Form about 70 small balls from the marzipan. Put aside covered with a tea towel. Chop both types of chocolate and melt them separately with 10 g of plate fat each carefully in a hot water bath.
Dip half of the balls into the dark chocolate coating. Drain, place on a piece of baking paper and allow to dry. Dip the rest of the balls into the white couverture, place them on the baking paper and let them dry.
Store well packed in a cool place.
