Shape approx. 1/3 (130 g) of the entire raw marzipan mass into 16 evenly distributed balls. Press in one whole almond at a time and shape into small cones. These small cones form the filling of the wasps' nests.
Knead the remaining 2/3 of the raw marzipan mass with icing sugar, cocoa and rum to a smooth mixture. Divide into 16 portions of equal size and shape each into small balls. Roll out the balls between 2 layers of cling film into circles about 3 mm thick.
Cut the circles once to the middle. Place the marzipan cones on each cut circle and wrap around them. Roll the whole thing with a light handshake on the work surface and form it into a smooth cone.
After this operation, immediately roll the cone in sugar and press it onto a biscuit. With the back of the knife pointing down, press horizontal grooves into the wasps' nests.
