Knead all ingredients except for the couverture with the mixer (or with your hands) to a smooth dough and chill for half an hour.
Then form small croissants on a floured work surface, place on a greased baking sheet or a baking sheet lined with baking paper. Bake at approx. 180 ° C top / bottom heat in the preheated oven for about 12 minutes. Let cool down.
After cooling, dip the tips of the croissants into the melted dark chocolate couverture. Place on a baking sheet and let the couverture cool down.
Tip: If the dough does not join immediately (this may be due to the flour), simply knead in a tablespoon of cold milk, it always works!
