Warm the honey (max. 75 °C) and let it cool down to about 40 °C. Knead the flour into the honey bit by bit. Place in an airtight container and keep in a cool place for a few days, better a few weeks. Let the dough reach room temperature a few hours before processing.
Mix spices, salt, potash and baking soda well. Place the dough on a floured work surface and knead with the egg yolk and spice mixture. Clean the work surface, dust well with flour again and roll out the dough about 1 cm thick.
Cut out hearts of 5-6 cm in size. Place on 2 baking trays lined with baking paper. Roll out the dough again and cut out more hearts until the dough is used up. Bake one sheet at a time in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see
manufacturer) Bake for 9-10 minutes. Let it cool down on the baking trays.
Coarsely chop the couverture, melt with coconut oil over a warm water bath. Coat the hearts completely or half with chocolate coating (dip) and place on baking paper. Decorate as you like with colourful sugar pearls or sugar sprinkles or sprinkle with chocolate sprinkles.
Allow to dry.
