In a bowl, combine water, starter and salt. Mix. Then add the flour and mix together just barely until there are no dry spots in the dough. (Don’t knead it)
Cover dough with a lid, and let dough sit at room temperature for 8-12 hours or overnight.
Preheat a Dutch oven inside your oven at 450 degrees for 30-60 minutes. (I recommend putting a pizza stone or baking sheet under the Dutch oven so the bottom of the bread doesn’t get too crusty & overcooked)
Right after you preheat the oven, dump dough out onto a clean, and lightly floured surface. Tuck, stretch, or roll the dough into a smooth ball. Pushing and pulling the dough in a circular motion helps it get into shape. (As shown in video).
Transfer dough ball to a piece of parchment paper, and cover with the upside-down bowl used to make the dough.
Let it rest one hour.
Remove bowl covering and lightly dust dough with flour. Using a sharp blade or knife, score the dough so the steam has somewhere to escape. Scoring also helps give the dough a direction to rise.
Transfer parchment of dough into a hot Dutch oven. Cover with lid and put in oven.
Reduce heat to 400℉ and bake, covered for 40 minutes. Remove lid and let the crust golden for 3-5 more minutes.
Remove bread from oven and put it on a cooling rack. Let it cool for one hour before slicing into it. (Slicing into it while it’s warm makes the bread gummy)
