Once the mixture hits 200F turn off burner, add vinegar and stir. You will start to notice tiny white particles.
Ladle the curds into a colander lined with muslin or a lightweight towel. Allow to drain. Once you can handle the cloth (it maybe too hot). Tie it in a knot and hang on the kitchen faucet and allow to drain for several hours.
I like this best served for breakfast with a little bit of splenda and lemon zest!
