So this is the tartine country loaf again, albeit a bit sped up. I feed the starter at 7am, kept it in the oven with the light on until like 1pm, then made the loaves as usual.
Major difference is that I've only been feeding my stater every two to four days, so the microbiome is all out of whack.
Not sure how this combination of decent oven spring, yet absolutely zero ear is possible, but here we are.
Its partner is in the fridge, I'm guessing it'll be significantly over-proofed
For the starter, I only put it in the oven if I'm seriously short on time, room temp is always better. Sometimes I put it in a warm water bath, but in the oven with the light on provides more consistent warmth, with no need to closely monitor it
