After a very nice success with a cheddar yesterday I thought I'd use my remaining 2 gal. of whole milk for a mozzerella. I also used for the first time Andy's beautiful horizontal curd cutter. The cutter worked great
but the cheese looks like a miserable failure
. Used Caldwell's recipe for traditional mozz and all went well until after I cut the curd, stirred and waited for the pH to drop to 6.1 or so. Well, it's 5 hrs. now and we're still at 6.7 (from an initial 6.8 indicating to me the culture was doornail dead.
I pulled out the packet of Thermo B (sold by Biena) and only then did I remember I had problems with this one before some months ago. Unlike Chozit cultures Biena doesn't put expy. date, only code and lot numbers. I remember emailing Biena back then seeing if I could get a date-made for this lot but never heard back. I purchased these cultures from Dairy Connection less than 6 mo. ago and they've been in the freezer ever since.
I should have tossed what was left of the culture when the first problem arose so I only have myself to blame. Being desprit I've thrown in some Thermo C just to see if I could anything going. Anyone have any ideas with what I can do with curds that don't acidify?
