For those who have access to raw milk. See the instructions for making clabber here:
http://cheeseforum.org/forum/index.php/topic,1927.0.htmlI've been using clabber to culture my cream cheese and finally had a batch turn out to be just what I wanted, flavor-wise, so I froze a quarter cup of it to use as culture for a future batch.
Wanting to make clabber-cultured cheese, but not having any clabber (too cold in the house for it to get going on it's own), I used that cream cheese culture to clabber a quart of milk. I kept the milk on top of the fridge to keep it warm enough to clabber within 3-4 days. I used half of the clabber to culture 5 gallons of milk and froze the other half in an ice cube tray for future culture.
I used whole milk for my cheese, which is a fake parmesan that I make by holding the cultured milk at about 70 degrees until it comes to a clean break, then cooking the curd. Long story short, I tasted the cream that had risen to the top by the next morning and found that it had a wonderful sour cream flavor. I skimmed it off, but it was thinner than I wanted, so I put the container on top of the fridge with a cloth over it. In two more days it was a bit thicker than pancake batter, so I put it into containers. I froze some of it and have kept some out for fresh use.
This is incredibly thick, almost like the spreadable cream cheese from the store, yet very smooth and rich. It tastes somewhere between sour cream, butter, and cream cheese, with the best qualities of all three.
I plan on trying to duplicate the results using some of the frozen culture with cream only.
