Step 2: Adding the Yogurt to the Milk
Cool down the milk to 120 degrees. The milk will quickly cool down if you put the milk saucer in a pan with cold water. Once the milk reachers 120 degrees, stir with a wooden spoon and then add the 1/2 cup of plain yogurt and mix with a wooden spoon for a couple of seconds to evenly distribute the yogurt bacteria.
