I was teaching an Eat Cheap! class to a group of women today, and the topic of making yogurt came up. I had just tried this slow cooker technique last week (and am getting ready to make another batch tomorrow), so I was able to speak to the accuracy and ease of this particular recipe. It makes just over a half gallon of plain yogurt, which is a great substitution for sour cream. It can also be mixed with all kinds of fruit, nuts and honey for a yummy breakfast or snack. I used whole milk for the base and plain Greek yogurt for the starter, but it looks like it’s fairly flexible.
