250 g rye flour (type 1150) 600 g wheat flour (type 1050) 500 ml dark beer
35 g yeast
20 g salt
Mix all the ingredients for the dampfl, cover with a wet dishcloth and let rest for at least 6 hours.
For the main dough, sift flour into the baking bowl, make a well in the center and pour in the dampfl. Crumble the yeast over the dough. Sprinkle salt evenly along the edge of the flour. Add the beer along the edge and mix well. Knead first with a wooden spoon or cooking spoon, then with your hands to form a firm dough (approx. 5 min).
