Buckwheat sourdough starter is strange.
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.
Stir and feed and all is good.
First image shows the layers before stirring.
Second image is 12 hours after feeding.
15g AP, 5g buckwheat; 5g starter; 15g water.

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).
I'm going to have to think about this. 🤔

At minimum I'll block the fridge vent into the cupboard but that won't be an all summer solution.
Wonder if I can force cold air up from the basement somehow? It may be easier to set up a second cupboard in the basement instead.

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 love it when hobbies intersect. 😂
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.

There we go. That's more than acceptable! 😋
It's 540g but larger in volume than the 570g first loaf.
It's slightly flat on the bottom because I spilled some boiling water intended for the steam tray directly on the baking steel. Not a good move. 🤦♂️
Buckwheat sourdough experiment part 1 completed. ✅👍👍

Buckwheat sourdough experiment part 2
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.

Interesting. This levain is definitely layered. Lots of very fine small bubbles in the top and lots of larger bubbles in the bottom.
Who knows what the heck this may affect? Not me! 🤷♂️

Yoik! 👀
That's one big loaf! And it's **not** overproofed. Thankfully it just dropped out of the banetton. This is looking good! 😋

That's one nice looking loaf. I'm really curious what the crumb will be like.
I'll try to get a more aggressive score into the second loaf. I was worried about the first loaf deflating on me but it seems to be a non-problem.
570g and about 8" long.

Levain is looking good. Nice and airy!
