In the morning, remove 50 g of ASG and slowly knead the sourdough with the other ingredients for 10 minutes. Only add yeast here if the sourdough is too weak. Let the dough rest for 30 minutes.
Knead the dough briefly again and form a loaf of bread. Preheat the oven to 250 ° C. Make a cut into the loaf just before shooting in.
