If left in the fridge for longer than three days it separates into two layers. I assume the white lower layer is the AP flour and the buckwheat endosperm. The purple-brown layer is likely the ground buckwheat seed coat and hull.
Buckwheat levain. The levain for today's loaves was buckwheat starter mixed with All Purpose and Whole Wheat flour. This levain is buckwheat starter with All Purpose and Buckwheat flour.
First pic is last night's levain and the second is the levain made today. They are both about 6.5 hrs into a 7-9 hour ferment.
Yesterday's didn't rise as much today's and was much 'craggier' in comparison. More buckwheat -> faster fermentation apparently.
Have addressed the flattened loaf issue by applying techniques from the excellent article by @rahix on functional 3D printing.
More perimeter (toughened outer dough), less infill (score exposed interior dough). Two smaller lame scores keeping a perimeter bridge across the middle of the loaf. Much rounder loaf as a result! 👍👍
Nearly the same weight. The first loaf was 525g, the second was 550g.
Not bad. It was a very sticky, slack dough so made a slightly flat loaf. You can see how slack the dough was by the huge bulge in the middle where the score cut gaped widest.
I really noticed the buckwheat smell when I took this out of the oven. Much more distinct than the loaves yesterday.
I thought I had conclusively proven that the buckwheat doughs fermented faster than my regular ones.
Decided to check the proofing cupboard temperature record. The faster ferment is because the cupboard is now much warmer than dead of winter, not requiring the heater at all. The temperature was well over my usual 21°C all night without heater assist.
The peaks are likely from the fridge running (air is vented from back of fridge into the cupboard).
Looking pretty good if I do say so myself. And I do! 😂
Three hours after mixing the final dough. Four folds, three in the first hour, one just a couple of minutes ago.
Then it's back in the proofing cupboard overnight with dividing and shaping between 8 and 9 tomorrow morning.
It's supposed to triple the original size of the dough and it's already about 1½ times. This may be a very big dough ball despite scaling it down by 20%.
Second loaf is even better! 626g vs 616g for the first loaf but a little larger as the lame cuts allowed the dough to expand even more.
I also think it's safe to drop the oven temp to 425°. There's some very light charring on the sides (tasty stuff that, actually) and the bottom is just a little blackened.
