First day 

2 dl (200 g) water 

2 dl (130 g) wheat flour 

1 dl (100 g) sourdough starter 

Combine the ingredients in a baking bowl. Cover with a tea towel and leave at room temperature (22–24°C) overnight.

the starter dough from the day before 

1 dl (100 g) lukewarm water 

1 tsp salt 

1 tbsp caraway seeds 

3 tbsp bread malt 

4 dl (260 g) wheat flour 

Blend lukewarm water, salt, seeds and bread malt with the starter dough. Add wheat flour and knead for 5 minutes. Cover with a tea towel and let the dough rise for 15 minutes at room temperature. Fold. Cover and let rise for 15 minutes. For the second and the third fold, repeat as the first fold. For the fourth and final fold, repeat the folding as before and shape the dough into a round bread. Put it into a proofing basket. Cover with a tea towel and let rest in the refrigerator overnight. 

Third day 

Take the bread from the fridge, let it come up to room temperature and rise until it has almost doubled in size. 

Preheat the oven to 250°C. Line a baking tray with a sheet of parchment paper and flip the bread on it. Score and put the bread in the oven. Reduce the temperature to 225°C and bake for 20 minutes.
