Sorry for not adding the recipe, I’ll do my best to describe it.

Feed the starter the night before, ~2tbsp starter, 200g water, 200g 50/50 whole wheat and white mixture

Day of, mix I think 100g starter, 400g white, 100g WW, and 400g warm water, leave for 6-8 hours at room temp

Autolyse: 740g white, 60g WW, 620g warm water, let sit for like 15-30 minutes

Final dough: add 0.5tsp yeast, 20g salt, and 360g starter to the autolyse mixture, mix thoroughly

I fold every like 15 minutes, 3-5 times.

After like 2 hours, when it’s juuuuust starting to get aerated, I divide it, do the bench rest, then shape the loaves.

This particular loaf spent around 12 hours in the fridge, then into a 475° clay baking vessel for 30, then put in the open for another 20
