Buckle up, friends! This is a do-it-yourselfer the likes of which we haven't seen around these parts since that whole duck prosciutto episode.
Since two of my favorite things in the world are a) making things from scratch that are readily available for sale elsewhere and b) cheese, you may be surprised it has taken me this long to make cheese in my own kitchen. But honestly, for most cheeses, it's kind of a crazy undertaking. You have to buy rennet or curds, there's often aging involved, and it certainly isn't a cost savings. But when I went to the Astor Center class on pizza-making a few months back, I happened to get a little hands-on cheesemaking experience as well.
We made mozzarella and ricotta in class. For the mozz, you buy the curds from Murray's, but all you need to make ricotta is milk and acid (like lemon juice, or vinegar). And then imagine my joy when I found this on Serious Eats: directions for doing it in the microwave. Yes, part of the joy of doing it yourself is tackling the process, but if the shortcut produces results that are just as good, I'm all for it.
So. Whole milk. Salt. Into the Pyrex. I made one batch with vinegar, but it's slightly more photogenic to make it with lemon. (More on the lemon thing in a sec.) Like so:
Pop the liquid into the microwave and rig up a strainer with a few extra layers of paper towels:
As you heat it, the acid pulls the milk solids into curds -- tiny, tiny ones -- and things start to separate. (Yours won't have the black specks; I used truffle salt just for fun, but the flavor didn't really come through, so salt-salt is a better call.)
