My GF likes to make her own yogurt. She likes to use the low-fat milk (wouldn't be my pick, but.....) and I think she just puts active yogurt into a container with milk and simply waits for the yogurt to make itself.

She also like buttermilk and makes that too, the same way.

Now.....why anyone would curdle milk on purpose is beyond me, but you guys (and she) can just do whatever you want.
