I steamed my oven in my usual way, described here in my post on how to steam your home oven for baking. But you can also bake in a pot or Dutch oven. Preheat your oven with a combo cooker or Dutch oven inside to 450°F (230°C). Remove your dough from the fridge, score it, and transfer it to the preheated combo cooker. Place the cooker in the oven, cover with the lid, and bake for 20 minutes. After this time, remove the lid (you can keep it in the oven or remove it) and continue to bake for 30 minutes longer. When done, the internal temperature should be around 208°F (97°C). Let the loaves cool for 2 hours on a wire rack before slicing.
