Okay, making homemade yogurt has been on my "To Do" list for quite some time now. I have just been putting it off but after I did some cost calculations, I will be making some this weekend! If you have not already checked out Stephanie's blog, please do so. She is the crockpot queen! Here's the link to her site with the full instructions on how to make yogurt in your slow cooker.

EDIT: I made this over the weekend and it made 64 oz not 128 oz. After thinking about it, I don't know why I thought 1/2 gallon of milk would produce a gallon of yogurt. Sorry about that and I have changed the original post to reflect that. Thanks! Oh, and making the yogurt was SUPER easy and it turned out great!
