Place the apricots and dates in the food processor. Pulse briefly until finely chopped and sticky.

Place the almonds, hazelnuts and apricots-dates mixture in a large bowl. Add honey, cinnamon, allspice, cardamom and nutmeg. Mix well.

To roll the sugar plums, pinch off about a teaspoon of the mixture and roll it into a bite-size ball.

Dust with icing sugar and refrigerate in single layer in airtight containers.
