Mix all ingredients and knead into a dough. Let rest in a warm place for 1 - 2 hours so that the baking soda works.
Roll out the dough on a floured work surface and cut out with molds or, since the dough is very sticky, always cut off a teaspoon of dough and press about 5 mm thick onto wafers with wet hands. Or roll out the dough under cling film as a flatbread on baking paper, bake and cut immediately after baking. Brush the dough with egg yolk before baking to give it a nice shine.
Bake the gingerbread at 180 ° C for approx. 5 - 10 minutes, depending on its size. It is essential to pay attention to the baking time so that they do not become hard.
Tip: The gingerbread can also be covered with chocolate.
