See how beautiful and crisp the hearth bread is. The holes are so beautiful. I did all the rises and the whole 24 hr sponge starter in the fridge. It was the night the electricity went out, and I couldn't open the fridge and check my starter until the electricity came back. Meanwhile I slept. The minute the electricity came back I woke up and ran downstairs. It was a good thing the starter was fine.
The only con to this bread is the high baking temperature. I can't do this too often, or else the electricity bill will "rocket sky high"
