Measure and sift flour into a large bowl
Measure and add starter and water into a separate bowl and mix
When the starter has mostly dissolved into the water, pour the mixture into the large flour bowl and mix for about 20 seconds
When the flour is mostly incorporated with the water, cover and rest for 30 minutes (this is the autolyse)
Add your salt to the dough and use your hands or dough hook attachment to incorporate all the ingredients by kneading
Once the salt is evenly distributed, cover your dough with a lid, moist towel, or clean shower cap
For the next hour, stretch and fold your dough every 15 minutes
For two hours after that, stretch and fold your dough every 30 minutes
After the stretch and folds time is up, cover and allow to bulk ferment for 4 hours or until doubled in size
Turn out the dough onto a clean work surface and pre-shape into two large balls or four small ones. Allow to rest for 15-20 minutes
Shape into loaves and transfer into a floured banneton or colander lined with a floured tea towel
Cover and place in the fridge for 8-10 hours
