I started by directly following Alexandracooks recipe (linked below), but I found I didn't like the bottom crust to be as firm or well done,so I started to change the process around...
I lowered the temperature to 450 F, and also did not preheat my Dutch oven.
I even placed a cool sheet pan under the Dutch oven to disperse additional heat from the bottom.
These changes made the cook time increase to 45-50 minutes depending on what add ins where in the bread. After this time, I make sure to temp the bread at 203-205 degrees F.
