The dough is prepared the night before. Sift the flour into a suitable baking bowl and press a pit in the middle. Pour the sourdough and a quarter of a liter of lukewarm water into the pit and stir in enough flour to make a thick pancake batter. Leave it in a warm place with the lid closed for one night.
The next day, add 1/2 liter of lukewarm water, salt, cumin and fennel and knead the dough until it separates from the hand. Now put the dough on a floured board, divide it in half and knead each half well repeatedly. It must be very smooth.
Later, give the two parts together again, put them in a suitable bowl, cover it and let the dough rest for about 2 1/2 hours. Later it is kneaded again, brought into its final give and put in a floured baking basket or on a floured board. The bread is left to rise for another 2 hours. Later it is brushed with water, poked with a fork and placed on a greased baking tray. Put it on the lowest level in the preheated oven.
