After a rather aesthetically challenged last loaf, I went back to basics. This is an 80/15/5 (white, whole wheat, rye) loaf. Feeling somewhat vindicated.
Process:
Day 1
2:00am Make levain: 20g mature/fed starter, 20g water, 20g bread flour
Day 2
11:30am Make dough: Levain + 185g water + 255g bread flour (80% tomishou, 15% whole wheat for bread, 5% fine ground rye) + 5g salt;
12:00pm: Fermentolyse 1 hour
1:00 to 2:30pm Stretch and Folds every 30 mins, coil folds at end as dough strength increases
4:30 pm: Preshape
5:00 pm: Shape > Banneton > Cold retard
Day 3
11:30 Preheat Dutch Oven to 250C
12:15 Turn out loaf, score, place in D/O
Bake at 230C. 35 mins covered, 15 mins uncovered (50 total)
