My New Method for Bread

I grease the cast iron and place the cold sour dough boules inside and cover them. They have incubated in the fridge for 3 nights. I shape them and put them in the oven and then turn it on to 450 F. In and hour they will be done but before that I take off the lid and rotate them, at the 40 minute point, baking uncovered for the last 20 minutes.
