Put the icing sugar, almonds and essence into a food processor.

Run the machine for a few minutes to get a nice texture. Add a tablespoon of water each time to get smooth marzipan. Be careful not to let the marzipan run too long, as this will release the oil from the almonds and make it too wet.

Make small balls of the marzipan and add different colours of food colouring to each ball. Knead well until you have a nice even colour. Make nice figures out of the marzipan.
