Okay, that does present a bit of a problem…..
I do know that if you get some fresh cream (or whipping cream) you can put it in a jar and shake the heck out of it. After the butter seperates from the liquid you are left with buttermilk (the liquid part). The only problem with this approach is that it takes a lot of cream to make a small amount of buttermilk. The plus side is that not only do you get the buttermilk you need but you also get a nice amount of fresh butter to eat.
We used to make butter all the time although we did have an electric butter churn to do it with. I would always just dump the buttermilk down the drain since I honestly can’t stand the taste of the stuff.
I have made cheese using buttermilk as a starter (one batch of cottage cheese) and it did turn out well. It does work, it’s just a little more labor intensive.
By the way…..what type of milk are you using for your cheese? Are you going with fresh milk, or store bought? If fresh, you have a good ready source of the buttermilk you need. The only thing I’m not sure about is if fresh buttermilk is the same as cultured. If not, then it will not have the bacteria needed to act as a starter. Maybe someone else will come along who has a better knowledge of this subject.
I really hope this information helps you out. The joy of making your own cheese and trying to perfect the craft simply can’t be overstated.
Also, stay in touch with this board. There are many helpful people who are more than willing to help with whatever problem or question you might have. I’ve only been here for a short while but I can tell you that the cheese I make is a better quality because of what I’ve read and learned here.
If you have any other questions, don’t hesitate to ask.
Have a great evening.
