My Latest (and best) Attempt

Hello all! Long time lurker and admirer. Been working on some of the finer details of my bread making and feel like I’ve made my best yet over the past few months of attempts.

Here was my recipe:
425g KA bread flour
50g KA whole wheat flour
25g spelt flour
350g water (plus 10g with salt)
11g salt

Fed starter at 8:30am (68-70 degrees in my house)
30 min autolyse at 8pm
Mixed in starter and salt with about 10g of water to help it incorporate)
Worked dough for about 5-10 min
4 stretch and folds 30 min apart

Baked at 8am the next day:
-preheated to 450 with Dutch oven
-baked for 30 min covered (also threw in a couple cubes behind parchment paper to help with blistering)
-baked 30 min uncovered at 425

Interested to hear your thoughts!
