Prepare all ingredients except ginger plums and cashews into a paste. Coarsely chop the cashews and the ginger plum together in the moulinette. Knead into the dough.
Rest the dough in the refrigerator for 1 hour with the lid closed. Shape into cherry-sized balls. Decorate each with 1/2 cashew.
Place the balls on a lightly greased baking tray and bake on the middle shelf at 180 °C for about 20 minutes.
