I love yogurt but it is so full of artificial flavors and colors and a bunch of other things I rarely buy it. I found a recipe for making it in the crock pot / slow cooker. It seemed easy enough. Get 1/2 a gallon of milk, dump it in the crock and cook on low for 2 hours. Turn the heat off, then cool for about 3 hours or to a temperature of 110 to 115 degrees. When the milk is cooled, remove a cup of the milk and stir 2 tablespoons of plain yogurt that has active cultures into it until smooth. Dump the mixture back in the pot, stir, cover and wrap the crock in a bath towel, then place the whole thing in the oven with the oven light on for 8 hours. Easy peazy, nice 'n easy.
Unless you are married to my husband. I put it in the oven at 9:00 pm last night. I went into the kitchen around 10:00 pm to find the oven light turned off. I checked my crock and it was still warm enough so I turned the light back on, and since DH was asleep on the couch, I put a note on the top of the stove "DO NOT TURN OFF THE OVEN LIGHT!!!" I got up this morning at 5:00 and wouldn't you know - the oven light was off! He said he didn't see the note. He did mention he couldn't figure out why the oven light kept coming on!
I had 2 quarts of yogurt milk. It was starting to thicken so I could have warmed the mix up to 185 degrees and made ricotta cheese, but I was up early to go riding, so I dumped it. I'm going to give it another go this evening although I am going to re-think my strategy for keeping it warm.
