TIPS
For the best results, make sure the dried fruit is at room temperature before blending it in a food processor.
Keep your hands clean and slightly damp before shaping the sugar plums into balls.
If you prefer a less chunky version of dough, add a little bit of water and blend until the nuts are finely chopped.
