Use a food processor to blitz the nuts.
Add the Medjool dates and blend again until mixed.
Add the cacao and salt, mixing again in the food processor.
Slowly add the water a little at a time till you have the right consistency - the balls should stick together but be easy to roll.
Scoop up about a tablespoon of the mixture at a time, rolling each portion into a ball with your hands.
Decorate the balls by rolling them in chica seeds or desiccated coconut or goji berries.
Place the balls in the freezer for about an hour, then store them in an airtight container in the fridge.
