This sourdough defies all logic

I did everything "wrong"
Photos don't do it justice, but it's my tallest loaf to date, it was touching the top of the Dutch oven

This was 200g of unfed starter, 400g 14% protein white Manitoba, 100g 13% protein wholewheat, 50g rye, 12g salt, 385g water.

Starter was unfed for a week and from the fridge

I did 5 mins of kitchenaid mixing, 5 mins rest, 5 mins mix, 5 mins rest, 5 mins mix, coil fold into a new container, 3 hours proofing at 30C, shape, banneton then fridge

Baked at 250C in preheated Dutch oven covered for 30, uncovered 20

I didn't add ice in the Dutch oven, I threw 100ml of boiling water over it

And yet here we are
