Measure and add starter and water into a large bowl and mix until starter mostly dissolves into water
Measure and add flour
Gently mix until it forms a rough shaggy dough
When the flour is mostly incorporated with the water, cover and rest for 30 minutes (this is the autolyse)
Add salt to the dough and use your hands (or stand mixer) to incorporate all the ingredients together. To keep dough from sticking, keep your hands wet when kneading, stretching, and folding.
Cover your bowl with a lid, a damp towel (or clean shower cap)
For the next hour, stretch and fold your dough every 15 minutes
For the following two hours, stretch and fold your dough every 30 minutes
After the stretch and folds are done, cover and allow to bulk ferment for 3-4 hours or until doubled in size
Turn out the dough onto a clean work surface and pre-shape into 3-5 balls. Rest for 15-20 minutes
While the dough is resting, line soup bowls with floured tea towels. Use as many bowls as you have balls of dough.
Gently build tension by shaping the loaves into tight little boules. Transfer into the bowls.
Cover and place in the fridge for 8-10 hours
