@rasterweb I preheat my oven to as high as it can go, about 500 F, at the bottom of the oven is a pan with stones. I put the loaf on a pizza steel, which also works with a pan. When I put the loaf in, I put about 300 g of hot water into the pan with the stone (be careful of the steam) close the oven door to 480 F. After 15 min I open the oven door to let out the steam, and change the oven to 450 C for another 30 min.
This will be „harrowing“ the first few times, because you’ll think you’re burning the bread. But it will be all good 😊
