Hey there! Could any of you give me a few advices what I do wrong, how could I have a more consistent, nice oven spring?
I use 450g of AP flour (12g of protein though), 300g of water and 150g of starter. I let the starter double (last time took around 4 hours), mix in the water and then gradually add the flour (yes, I do not do autolyse anymore). Later upon kneading I add 11g salt and knead it into a nice smooth ball. Let it rest and perform 3 sets of coil folds (30 minutes between them). Following that I take a small amount of the dough in a jar as a sample.
Around 6 hours later this has doubled, although I still couldn't see the signs of a successful bulk fermentation on my dough, it was still a bit too sticky so I waited and extra 30 minutes. Then I preshaped, shaped, had some issues with the tension though and put it upside down in the kitchen towel and basket for 20 hours before baking it on 230 C for 30 and 200 C for 20 minutes in a pre-heated dutch oven (gas oven so even with a thermometer the temp control is a pain). And this is the underwhelming result.
I have made great loaves with this recipe before however, this lack of consistency annoys me (I recently moved and cannot get the same quality). I suspect that I mess something up around the bulk fermentation.
