Just a tiny update on the sourdough process. After 1 day some small bubbles start to form. I've fed the dough using again 50g flour and 50g water. On day 1 I don't remove old dough, as I think the number of absolute bacteria is still low and needs to be increased first.
We're having about 19 degrees here in the house. It's not optimal but it seems to work. Could be that it's slowed down a little bit because of the temperature. Anyways, the bacteria are pretty resilient, so no need to worry. Might just take a day longer 😉
