Des got me a cheese making kit for Father's Day, and we just got around to making some cheese from it. The process is slightly less arcane than it sounds, as the kind of cheese we made - mozzarella - is the second-simplest cheese in the world (ricotta is #1 by my estimation). For those curious about the steps, they are:
- Heat milk with a tiny amount of citric acid to 88F.
- Add a tiny amount of a natural enzyme, rennet, to the warm milk.
- The rennet performs a minor chemical transmogrification, gelling the milk into something that resembles a loose custard. You wait a few minutes while this occurs.
- The custard is just milk solids suspended in a yellow fluid called whey. You drain off as much of the whey as you can. This is tricky but it turns out a simple wire strainer (and some patience) works great.
- You now have a big bowl of ricotta. You could stop here, but if you want mozzarella, you heat the results in a 185F water bath. You dunk chunks of the prenatal cheese in the water, getting it hot enough to melt. Then you knead the hot cheese, developing the texture and forcing out the remaining liquid.
- Put the cheese in ice water to cool. This is important if you want the cheese to maintain its shape.
Our next stop is ricotta. We've already been there, but more as a rest stop on the way to its more advanced sibling. I'm willing to try other cheeses if anyone is particularly interested in other varieties.
