In This Recipe
Preheat oven to 205C/400F.
Dissolve the Pottasche and the Hirschhornsalz in 1 teaspoon milk in seperate small bowls. These two should not be mixed together before they go into the dough.
Chop the candied citrus finely or run it through a blender.
Mix all the ingredients but the Pottasche and the Hirschhornsalt and the wafers into a smooth dough.
Add the Pottasche and knead for 1 - 2 minutes.
Add the Hirschhornsalt and knead for 1 - 2 minutes.
Spread the wafers out on a parchment lined baking tray.
Wet your hands, take about one tablespoon of dough, roll into a ball, set it on a wafer and spread it out so it covers the whole wafer and has the shape of a low dome.
Once you have used up all the dough (or as much as you can fit on one baking tray), bake for about 14-17 minutes.
When they have cooled down you can glaze them with chocolate or a sugar glaze.
