Lemon Kefir Cheesecake

Kefir is a relay race. Over several periods in my life I would get the urge to make it myself, so I would get a small amount of Kefir grains. But because it’s alive, it grows over time, and after a few weeks you find yourself buying milk by the gallon, and at that point really getting sick of it. When that happens I usually try to give the grains away instead of throwing them, just to keep the organism circling around until next time I get the urge.

This recipe is a good way to use a lot of Kefir. Once you have half a gallon, you can strain it in a cheese cloth to make about a quart of Kefir cheese. The original recipe called for 750ml of 5% fat fage + 300ml of yogurt, but I find Kefir cheese to be a very good substitute.
