Yes I realize that crockpot yogurt sounds gross but it's not. It's not hard, you can do it in your sleep and it tastes like no other. Other good reasons to make your own yogurt is that it's cheaper and you can control the ingredients. I'm big on the last one and would still do it even if it wasn't cheaper. Our family eats a lot of yogurt and I do mean a lot! My youngest, AJ would seriously eat yogurt all day every day. Since I don't buy foods with chemicals or additives or preservatives or anything I can't pronounce, the yogurt I buy is expensive. Plus, sometimes I can't get it at my local grocery store.
I had no idea that you could even make yogurt at home until one day I was chatting with Sister Chef and telling her about my breadmaking. She then told me how she had been making her own yogurt. WHAT??? You can do that? It took me about a month, but I was all over that. She bought a yogurt machine to incubate hers in but it doesn't hold a lot which is fine for her since it's just her. I needed to make larger batches so I started scouring the Internet to see how I could do it. After reading eleventy billion (yes that's a real number in my house) sites I finally came up with something I could do.
Add a cup of the warmed milk
Give it a stir.
Until it's nice and blended.
Add the yogurt/milk mixture back into the crockpot.
Give that a stir. (never fails, I always get a sideways picture or 3)
Then let it sit for 5-7 hours. You need to keep the temperature around 110 degrees. I wrapped my crockpot in a towel and after 2 hours I turned it on for 5 minutes and then back off. I've heard of people putting the crock in the oven with the light on, or leaving it on the counter overnight. (see you can do it in your sleep!)
When you open the lid you'll be delighted to find this! Don't worry about that liquid stuff you see. That's the whey. You can stir it into your yogurt OR
