[ Autolyse: 1 hour 35 minutes.]
7:16 pm. Folded in 44 grams of 100% hydration starter (generic AP flour), 8 grams water, 17 grams generic AP flour. Overall hydration so far: (531+22+8) / (625+22+17) = 561 / 664 = 84.5%
625 / 664 = 94% whole grain.
7:46 pm - 7:51 pm. Stretch and fold, and fold in 1 tsp ground bread spice. (By pre-ground volume: 1/3rd coriander, 1/3rd caraway, 1/3rd fennel.) Spices were raw, not roasted.
7:57 pm. added 5 grams water. 566 / 664 = 85.2% total hydration.
Total weight, calculated: 1239 grams.
8:21 pm: Stretch and folds.
8:53 pm. Stretch and folds.
9:25 pm. Stretch and folds.
9:44 pm. Stretch and folds.

[ Bulk ferment, 4 hours, 7:16 - 11:16 pm ]
Weight, measured: 1227 grams.

Sept. 22, 2020.
6:14 am. Take out of fridge. Went back to bed.
9:08 am. It rose too much at room temp. Put back in fridge.
9:09 am. Start pre-heat of oven and Lodge cast iron combo-cooker, target 495/475* F.
Oiled heated pot with grape-seed oil, dusted with fine semolina. Forgot parchment paper again.
[ Final proof, 11:16 pm - 9:56 am, 10 hours + 40 minutes ]
9:56 am. Bake covered, 495/475 F, 10 minutes.

10:16 am. Bake covered. 450/430 F, 10 minutes.
10:26 am. Bake UNcovered, 420/400 F, 20 minutes.
10:46 am. Bake uncovered, 400/380 F, 10 minutes.
10:56 am. Internal temp 210.0 F. Total bake 60 minutes.
Virtually no oven spring at score lines, they weren't deep enough. There was some oven spring over-all as evidenced by exapansion cracks throughout the top crust. Ergo, final shaping was too weak and didn't form a good gluten skin/cloak.
I should have left it in fridge, as the expansion during the room-temp final proof was too much.
I always let boules cool upside down. This was the first time the upper crust collapsed.
