Add the flour, water, oil, and sourdough starter to the bowl of a stand mixer and mix using the dough hook attachment for 3 minutes or work the ingredients together by hand. Cover and allow the dough to rest for 30 minutes.
Add salt and mix again using the stand mixer for 3-5 minutes or again by hand until the salt is fully incorporated. Cover and allow the dough to rest for 30 minutes.
Perform 3 sets of coil folds allowing 30 minutes of rest in between each.
After the last coil fold, cover and allow the dough time to bulk ferment. Let your dough rise 2-6 hours depending on the temperature. For best results, do not let the dough proof for more than 8 hours at room temperature.
Once the dough has doubled, place it on a floured work surface and divide it into 4 equal pieces. From here you can shape and bake or freeze each ball of dough according to the directions below.
