The recipe is enough for one large or two small loaves of bread! Prepare the sourdough the day before, it is a little drier, but it is intended that way! Cover the bowl with cling film and leave to mature in a warm place for at least 12 hours. Dissolve the yeast in the water the following day. Use the food processor with a dough hook to knead the sourdough, the yeast water and the remaining ingredients into a smooth dough (6 minutes slowly, 4 minutes quickly). Let rest for 10 minutes.
Then place the dough on a floured work surface and work with floured hands as follows: pull into a rectangle, fold the tips towards the middle, fold from 12 o`clock towards the middle, turn 180 ° C, repeat. Now fold it up once, press the ends together, let it rest for 30 minutes, then repeat again.
Place the folded dough upside down in a floured proofing basket (with the open side up). Cover and place to cook (approx. 50-60 min.) Tilt on a baking sheet lined with baking paper. Cut once lengthways. Bake in the preheated oven at 250 ° C with a lot of steam for about 15 minutes, until the desired browning, then drain the steam (open the oven door briefly!) And bake at 200 ° C for another 40-45 minutes. Knock test!
