Ingredients for the flatbread
Ingredients for the herbed quark
Mix the water or sour milk with the flour to form a smooth dough, which you leave to swell overnight. Now add flour, salt, and a little butter to this pre-dough. The flatbreads are particularly tasty if you substitute a third of the flour with grated or finely chopped hazelnuts.
Now carefully place the stone slab over the embers of your fireplace. To make it stable, you should place some stones between the embers and the slab. Form tennis-ball sized balls from the dough and after flattening place them on the hot baking surface. Now let your flatbreads brown slowly, and turn them over once.
For the herbed quark, finely chop the herbs and mix with the remaining ingredients.
