The instructions for the dried milk called for 2 tablespoons in a cup of water. Since I was starting with milk instead of water, I decided to use just 1 tablespoon per cup of milk. To mix up each batch, I put a tablespoon of dried milk in a small glass mason jar, added about 3/4 cup of milk, put the lid on, and shook vigorously. The goat milk powder in the cow milk did not dissolve very well and required some extra whisking. The others incorporated pretty easily. Then I added 1 tablespoon of the yogurt and topped up the jar with more milk. I mixed up all the batches at the same time, and put a lid on each jar. (I always culture with a lid on, although it is optional.) Then I sat down and watched them culture for 12 hours. Not really! I just put them in the cabinet where I usually culture my yogurt, and made a note to check back in 12 hours. What would be your guess for how each one set up? See if you’re right in Part Three of the Great Yogurt Experiment!
