For the Kraft balls, coarsely chop the plums and apple rings.
Mix together with the flakes, grated nuts, honey and vanilla and blend finely with a hand blender or pass through a meat grinder.
If necessary, add a little water.
Form balls, roll in the coarsely chopped nuts and place on a baking tray covered with baking paper.
Let dry in the oven at 60°C for about 30 minutes.
