I used some points of this recipe for making a sourdough loaf, I tweaked the cooking times I use to match yours (usually I do 25 min covered at 250, then 20 mins uncovered at 170) and I was really happy with the result! I sprinkled water on the dough right before cutting suits to give it a nice bubbled crust effect. Thanks for posting!
I keep wanting to come back and change little things. There's soooo many nuances that change a whole lot. Which everyone here probably knows. But I learned a lot from ChainBaker on Youtube, so check his stuff out. His video's are relatively short, but packed with a lot of information.
