I found a housekeeper. A little, old, Greek woman, who cleans other houses on our block. She is pretty good at cleaning, too! When I first met her, I asked her if she knew how to make Greek yogurt (one of my favorite foods of all time). She said she'd teach me.
So she showed-up today, to clean. And teach me how to make Greek yogurt. And brought home-made baklava. SO FABULOUS.
First she warmed a quart of whole milk, until "the milk come up." (I'm still trying to figure out what this means). Then "let it cool until you can stir it with your finger 20-times." And then she added three, large spoons of plain, whole yogurt to a small bowl, mixed it up and added it to the milk. Then she said "cover it in a blanket and leave to tomorrow." So she wrapped-up my bowl of yogurt-to-be, in a fleece blanket, very carefully, like a baby, and patted the top lightly, saying "good luck" - to the yogurt, not me.
