Roughly chop the cherries. Mix flour, baking powder, sugar, vanilla sugar, speculoos spice and 1 pinch of salt. Add butter and eggs. Mix with the whisk of the mixer. Add cherries, almonds and raisins.
Knead into a dough with your hands. Cover and chill for about 30 minutes.
Preheat oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer). Line a baking tray with baking paper. Quarter the dough and form each into a roll (approx. 15 cm long). Place on the baking tray with a little space between them.
Bake in a hot oven for about 15 minutes. Let them cool down.
Line two trays with baking paper. Cut each roll into about 20 thin slices. Distribute on the trays. Bake one after the other at the same temperature for about 8 minutes. Take out and pull off the baking tray together with the paper.
Let it cool down.
Chop the couverture and melt in a hot water bath. Dip half of each Cantuccini in the couverture and let it dry.
