Place the 1/4 cup of pistachios in a food processor and blitz to a rough crumb.
Pour the crumb on to a plate and set aside.
Put the cinnamon, all spice, roast almonds, pistachios and walnuts in the processor and blitz in to a rough crumb.
While the machine is still running, slowly add the rice malt syrup and blitz until combined.
With clean hands (wet if necessary) roll the mixture in to serve size balls and roll each one in to the pistachio crumb set aside earlier.
Place the balls in to the fridge for 30 minutes.
Before serving, take the balls out of the fridge for a few minutes to relax.
Serve with black coffee or tea
