This question came in recently via the Forum:
I do have a question as well. Trying to make ricotta today, I used 2% instead of whole milk. Added some citric acid and salt, heated to 195, and couldn't get the curds to separate, save a few lonely stark white ones floating on the top. After a while (since I assumed all was lost, although I wasn't sure why) I added some rennet to experiment. It separated, those curds sinking to the bottom, wispy off-white. I let them sit and then drained into butter muslin, which is now hanging to drain. Not sure what the finished product will be, or where I went wrong. Should I just not have used 2%?
I don't think a low-fat milk would entirely prevent the proteins from coagulating, it would just likely lead to a drier, less creamy texture. Perhaps the milk was ultra-pasteurized? If you have any further advice for Heather, leave a comment!
