Well I am using an immersion circulator and a water bath but here is the problem that I run into on all my tries thus far:
Say the desired temp is 105 like in the recipe and I get my waterbath to hold between 104.8 and 105.2 (my typical accuracy for long holds) which should be good, but the outer portions of the curd obviously set earlier and then slow the heat transfer so that even after the 30-45 minutes of bringing it up to 105, the center might still only be 98 degrees (or even lower with the 2 gallon batch of milk).
-So my problem is that the next step is to hold the curd at that 105 degrees for some amount of time but I don't know when to start the timer since not all the curd is set. Should I wait to start the hold process until I get all the curd to that temperature (which could take 1.5 hours)? or would this release too much whey at this point?
I also have been trying a store brand milk, but I am going to get the local grassfed and stuff thats only a few days old and see if that makes the difference too.
