This was a total flop for me. I have heard of people making yogurt in their crockpots and I thought this would be a good idea. I used the Good Eats recipe but changed the cook times to the crockpot recipe. This resulted in thicker milk like substance, but not quite yogurt. It just didn't thicken up. So, I tried cooking it a little longer which resulted in a tan colored mess that didn't look or taste like yogurt. It was more like spoiled milk. A total flop. I do want to try again, but if anyone has tips for making yogurt, please pass them along!
