The next morning at 7:00 a.m., remove the bin from the fridge and gently pull the dough out onto the counter. Lengthwise, fold one side of the dough over itself and then fold the other side completely over that. Next, roll the dough up into an oval. Take the bin, flip it over and place it over the dough. Let the dough rest for 30-40 minutes.
At 7:40, after the dough has rested, re-shape / re-tighten the dough back into an oval. Gently pull it along the countertop to create surface tension. Flip it upside down and place it in a lightly floured oval banneton so the seam/bottom is on top. Cover it with the plastic shower cap and let it sit on the counter for 1 hour, basically from 8:00 a.m. - 9:00 a.m.
After the hour is up, place the covered banneton back in the fridge for 6 hours.
At 3:00 p.m., after the 6 hours in the fridge, take it out of the fridge and place it in the freezer. Put your cast iron dutch oven in the oven at 500 degrees and begin heating it up.
Between 3:45 p.m. and 4:00 p.m., remove the banneton from the freezer. Gently tip the bread loaf out onto a circle of parchment paper. Use a lame to cut one long cut from end to end holding it at a 45-degree angle while slicing.
Next, transfer the loaf to the hot dutch oven. Place the loaf in there with two ice cubes and replace the lid. Bake for 20-25 minutes with the lid on. Then, remove the lid and bake for another 10 minutes. The loaf is finished baking when the internal temperature has reached 200 degrees.
Remove it from the oven and place it on a cooling rack to cool. Wait until it is fully cool to slice! Enjoy with butter, or make a grilled cheese!! Yum!
