Poolish Quantity vs IDY Experiment
« on: May 29, 2023, 05:24:10 PM »
So, some lab work, to nail down a tricky fermentation issue.  We begin with a hard fail


At issue, the quest is for full toasty flavor and light open crumb. Two features I usually have covered, but sometimes am falling short.


I'm using a fairly high hydration final dough and shooting for a poolish followed by 5+,day CF


At issue is that  even working at a very low IDY to work the extended time and at a nominal 32F, I'm still overfermenting before my schedule.


When I use a very short RT period after mix before CF, the dough has failed to develop. I'm at .02 %
 So I tried reducing my poolish percent from.my usual and high 43% to 30%


The dough seemed to still be moving way too fast, and yet by day 5, I totally failed and turned to goo.


85% Red Rose, 15% Trailblazer T85.  70 hydration, 2 oil, 2.7 salt. 2 sugar

So, extreme over fermentation but at reduced poolish, worse ? Or did the reduced poolish not create enough yeast activity to go the distance? I never had this result at my poolish level.


Try more IDY? Back where I started and beyond.


Final dough temp here was 68F. So pretty cool or at least not warm.

Definitely overfermented.   Its not lowering the poolish that caused this, though.

I wonder if I was sleepwalking while mixing and did.something crazy, because, right , the poolish was less and the fermentation more? Possible that making a change from routine numbers let a gremlin into the kitchen!



Need to repeat this as close as possible and report back.


Edit for earlier post: the dough turned to goo. I, personally, did not  :-D

Are you using any DMP, Bill? Guessing not since you did not list it.


As I recall, you typically put all of the formula yeast into your poolish. At 30% poolish, your 0.02% for the total dough becomes nearly 0.07 for the poolish flour.Might be something to that

Thanks for thinking about this Tony....its been a head-scratcher!


Actually 30 has been the reduced poolish amount I'm testing here while ordinarily I've been at 43 percent, well within the maximum recommendation of 50%.


I do use DMP on occasion but not for my long dough..mostly if I'm doing same or next day or two ( and adjust amount accordingly).  But that hasn't been at play here.


A test is well underway, though. I may be onto something.
And if I'm correct, I'm going to look like an idiot.


Of course, that isn't anything new for me. :-D

My a$$. Id like to sell tickets to that. It would be so rare the tickets would go for big bucks.  :-D
Im looking forward to seeing what you learn, you always figure things out.

Okay..
Poolish the same , IDY, the same, HR the same. Pizza below from day 7, .02 total IDY.


So what was the issue? Tony, I told you so: I'm an idiot ;D


That 32 F fridge temp? Maybe the air was 32, but the dough containers were 36-38
And while I thought keeping the fridge pretty empty was a h
good idea, I was dead wrong. Also coils needed a good cleaning.


So back in the saddle.  :)
