sourdough starter - watch the video to see (active and bubbly)

water - watch the video to see (lukewarm for mixing)
salt - watch the video to see (for flavor)
Instructions
Prepare dough: Mix sourdough starter, bread flour, water, and salt to form dough. Allow to ferment until bubbly and active.
Retard fermentation: Place dough in the fridge to retard fermentation for about 12 hours.
Remove and prepare for scoring: Take dough out of the fridge, flip it, and dust with some white flour powder.
Score the dough: Using a razor blade, knife, or scissors, score the dough at a 45-degree angle. Do not score straight down or completely sideways. If the cut is not deep enough, cut again.
Bake covered: Place the scored dough into a very hot pot and cover it to trap steam. Bake for 20 minutes.
Bake uncovered: Remove the cover and continue baking to develop a brown crust and finish cooking. If the ear has not formed after 20 minutes covered, it will not form.
