Serendipity but Success

Using the buttermilk starter, cheese thermometer, and Carroll's book, all ordered from you, I embarked upon making the moist buttermilk cheese on page 68, this with cow's milk. Well, it never got very solid, so I switched to the dry buttermilk recipe on page 69 and adding rennet and heating did the trick. Now it was a question of what to add to this cheese with an underwhelming taste. I had bought chives but even chopped up, they seemed a bit past their prime, so I also added some finely chopped red onion. Along with a little cheese salt (also from you) it is now a tasty spread for a bagel! And, the red and green flecks make the cheese make it ready for Xmas!

It is the best. It's so easy to make your own buttermilk, My husband likes it better than store bought for drinking. I like it for baking and cooking. I make a lot of it. New England Cheese Making Supply Co. sends me fresh products and good delivery. The dogs love dairy too. My husband gives them some once in a while. They love it! In 24 hours I have enough buttermilk to last till I am ready to make more and I never run out. I don't have to worry about getting it from the store( which they are usually out of.) I can't even get cream. It's hard to find heavy cream that is usually in stores. I don't have to worry about the stores carrying my dairy products. I make my own with the help from The New England Cheese Making Supply Co.

This makes great buttermilk! We don’t get to store very often that sells buttermilk, and it’s far away. This is much better and I can make some anytime I need it. Also used some of the fresh day old buttermilk as a culture to make some cheese curds, they were great!
