**next day**
Preheat over to 450° with baking stone and pan on rack underneath.
Begin boiling cup of water.
Turn out dough onto peel or baking paper. Brush off excess flour. Score as desired.
Place dough on baking stone. Pour boiling cup of water into pan and quickly shut door.
The steam inside the oven gives the bread it's nice golden-brown crust. You want to prevent as much steam as possible from escaping. I pour the water with a measuring cup instead of the kettle. It has a larger opening, which means I can pour faster, which means the door is open a shorter time. Wear an oven mitt to prevent steam burns.
Bake for 15 minutes.
Turn down oven to 375°. Bake for additional 20-25 minutes until golden brown and center of loaf reads 190°F.
Remove and cool completely on rack.
Additional Notes
Really easy sourdough recipe. Mix and then fold it a few times over several hours and give it a nice slow overnight rise.
