Tom,
I'm hand mixing dough in batches in the 10K range.
I do a high % prefermented flour levian style mix with SD (2.5%) and trace amounts (.2-.3%) of IDY. The method is based on Italmil's scrotchetella process.
I mix the prefremt, chill 12-18 hours then mix final dough by hand, let rest 1 hour. Perform 5-8 strech and folds over 2-4 hours RT. Then I scale, ball and chill for a 2-4 day CF.
I'm really liking the process and results. Since I've had to scale up my batches beyond what what my nutrimil will handle; it's been simpler to hand mix. That requires the prolonged strech and fold to fit my work flow. So I feel like direct mix, ball, chill doesn't fit well.
My target FTD is 70-75 and ambiant temp is 75-78.
It requires me to be at the mercy of the dough to moniter the mixing and RT strech and fold so it ferments at a perdictable rate.
What's the best tatic improve work flow predictablility?
The ideas I came up with are:
- shoot for a lower FDT like 55 or 60
retard the dough during the strech and fold stage then ball and CF
bulk CF 24 hours then ball
I'm open and the goal is less finicky work flow.
here is the formula:
100% peak performer/ t85 / fine durham blend
65% water (sometimes I do Roman style with 75% h2o as well)
2.5% starter
.3% IDY
3% salt
5% oil
I preferment 50 % of the flour with 30% h2o, .2% IDY and cold ferment 12-18 hours.
Then mix in remaining ingredients, rest, strech and fold RT 2-4 hours, ball, chill, CF 2-4 days.
Bake in a blackstone at 650-700
