Oh that sounds great! I’d rather it be oven ready like that. How much starter do you think it needs?Mix it up tonight and let it proof for an hour. Shape it into the loaf pan and then let it bulk over night in the fridge covered with plastic wrap.
In the morning, set up a 9x13 pan on the bottom shelf of the oven and pour boiling water into it. Put the pan with the dough in it on the top shelf and leave it for 40 minutes to warm up. After 40 minutes, take both pans out of the oven and warm up the oven to the temperature in the recipe.
When the oven warms up, remove the plastic wrap from the pan and bake the bread.
