For the gingerbread dough, lightly simmer the honey, sugar and vegetable fat together in a saucepan until the sugar has dissolved. Allow to cool.
Sift the flour, cocoa and spices into a large baking bowl. Add the cooled honey mixture, the eggs and the potash dissolved in rose water. Knead everything into a smooth dough and refrigerate for a few hours.
Now roll out the dough on a lightly floured surface and cut out the desired shapes or cut them out with stencils.
Bake the gingerbread in a heated oven (200-225 °C) for 15-20 minutes, depending on the thickness of the pieces.
Slightly deformed gingerbread can be trimmed when it comes out of the oven and is still a little bit soft.
