I added a metal bowl with water to the bottom while it was preheating (as always) but I also poured about 1/4 cup of water onto the bottom of the oven after putting the loaves onto the baking stone. so I got a huge pop of steam. About 5 minutes later, I sprayed the side walls of the oven with a mister. I took out the bowl at 12 minutes, turned down the heat and rotated the loaves, which resulted in a blistery, flaky, delicious crust.
I feed my starter once a week. Usually 1:1. This particular feed - I gave it 100gms starter, 160gms bread flour, and 140 grams water. It was so vigorous and happy! It still gave me a strong sour flavor in the final product that made for an absolutely delicious crumb.
It's my best loaf yet!
