We have no store in the area that sells milk with cream on the top. For that, you have to drive to the farm and get the farmer to sell it to you on his land. Laws against transporting raw milk to sell/distribute.
Nearest place is 40 miles from us. We can't even get whipping cream that is not ultra pasteurized. Organic Valley has an option that has milk with cream on top, but our Walmart doesn't stock it.
Can you make butter from ultra-pasteurized cream?
I know that many directions for cheese making indicate that you should not use ultra-pasteurized milk for that.
