In a quart jar mix the sourdough starter, water and oil. If using honey, add it here.
Mix 3 cups of the flour, sugar (if using instead of honey), and salt together.
Mix wet into dry. (If using any amount of whole wheat in here, let it sit 20-30 minutes to "autolyze.")
Knead it for a few minutes, until it passes the window pane test.
Return dough to the bowl and cover.
Let it sit 8-18 hours depending on how tangy you want your bread.
Scoop dough out onto a floured counter. Form a loaf by tucking the sides of the dough underneath in on itself until you've got a smooth tight loaf. It will take about 5-6 times.
Dust the top of the loaf with flour.
Using parchment as a sling, set dough aside to rest (uncovered!) for 30 minutes to 3 hours. I usually aim for about 1 ½ hours.
30 minutes before you want to bake, put your pot in the oven, and turn the oven on to 500°F.
Deeply slash the top of the loaf (¾-1" deep) .
Take the pot out of the oven, lower the dough into the pot, put a lid on, and return to the oven.
Bake for 25 minutes, take the lid off, and then bake for another 5-15 minutes or until it reaches an internal temperature of 195°F.
Transfer the bread to a cooling rack.
Let it sit for a minimum of 15 minutes, preferably 30-60 minutes to allow the gluten structure to set up for you.
