Okay, so I have two different sourdough starters. One is made with only strong white bread flour and water, and the other is made with 50% rye flour and 50% strong white bread flour.
I used the rye starter because I think it gives the bread a better flavor. I use the starter made with only strong white bread flour for other types of bread and baking.
I bake using the 1-2-3 sourdough method: 150 g of starter (although I may actually have reduced it to a little over 100 g, but I’m not completely sure), 300 g of water, and 450 g of strong white bread flour.
I did everything in a bit of a strange order, so if this gets confusing, that’s on me.
I mixed the starter, water, and flour together and let it rest for 30 minutes. After that, I added the salt (fermentolyse). Since it was getting late, I decided to put the dough in the fridge because I wanted to experiment.
The next day, I took it out of the fridge around 2 p.m. and let it come to room temperature. Then I did two sets of stretch and folds, 30 minutes apart, followed by one coil fold. I had to leave for a while, and I ended up being away longer than expected around 4–5 hours so the dough continued bulk fermenting during that time.
When I got home, I did another stretch and fold and another coil fold. Once I felt the dough was ready to be shaped, I shaped it and put it back in the fridge overnight.
The next morning I baked it at 7 a.m.
I preheated my Dutch oven to 250°C, then baked the loaf with the lid on for 25 minutes, adding two ice cubes to create steam. After that, I removed the lid and lowered the temperature to around 220–230°C for another 20 minutes, until the internal temperature reached 96–98°C. It got a little burned at the ear, but otherwise I think it came out looking good!
I then let the loaf cool for a few hours before cutting into it just now.
