Place the dates and prunes in a bowl and cover with boiling water
Leave to soak for around 15 minutes, or longer if you have the time
Drain the dates and prunes and add them along with the other ingredients into a mini food processor/chopper. If you wanted to you could quadruple the recipe and use a food processor or blender for this step
Blend until everything is combined and sticky
Either place the mixture into a small dish and press down or remove small pieces, roll in your hands and place on a tray (it is easier to do this if you cool it in the fridge for 15 mins or so)
