Mix together baking ferment, 110 ml water and 100 g wheat and leave to stand for 24 hours at room temperature in a tall, covered container. Then add 150 g wheat with 50 ml water and let stand again for 24-48 hours. The dough has to rise.
This approach can be kept in a jar in the refrigerator for up to six months.
It is made once, after which half a cup of the pre-dough is removed for each baking process and stored in a screw-top jar in the refrigerator for the next baking process.
Pre-dough:
Take the basic batch out of the refrigerator and let it reach room temperature for approx. 2 hours.
Mix wheat with hot (manual test must be possible) water. Add the basic mixture and stir everything for approx. 10 minutes to a soft dough. Cover and let stand at room temperature for 12 to 24 hours.
Remove half a cup and store in a screw-top jar in the refrigerator for the next baking.
Main dough:
Mix wheat and rye flour with hot water. Add the pre-dough and the remaining ingredients, mix everything to a soft dough and knead for approx. 10 minutes. Cover and let rise for at least 60 minutes.
Put the dough in the greased and flour-dusted pan and let rise again for at least 60 minutes (must be approx. 1/3 higher).
Preheat the oven to 230 ° C and put hot water in the oven.
Bake for 15-20 minutes at 230 ° C, then finish baking for 30-45 minutes at 200 ° C.
The bread is ready when it sounds hollow when you tap the underside of the bread.
