Trying to make yogurt with an Instant Pot

                Apparently there is always more to learn about yogurt. I was recently gifted an exciting kitchen gadget—an instant pot with a yogurt setting! I was so excited to try it, and on that weekend I made a batch of yogurt. Because I had always depended on a thermometer to make yogurt, I tested the temperature of the milk and yogurt throughout the process. After heating the milk, the temperature was only 165⁰ F. I tried to rerun that setting, but it would not heat much further, so I used the regular slow cook function to get the milk to 180⁰ F. Then, I cooled the milk as I usually do, added the starter, and set the machine to the fermenting setting for 14 hours. As soon as it beeped to let me know it was finished, I checked the temperature, and it was below 100⁰ F. The texture was much thinner than I get when the yogurt ferments at 155⁰ F. The yogurt still tasted good, but it was not quite the texture I was hoping for. 

                I contacted the Instant Pot customer support, and their answers were not particularly helpful. I am still unclear if they intended the Instant Pot to ferment yogurt at below 100⁰ F or if the pot does not work as it is supposed to. At one point they offered to send me a new heating element, but I want to see if I can get it to work well enough with the one I have first. I am going to try to ferment it for 18 hours to see if fermenting it for longer can make up for the lower temperature and still result in a thick yogurt.
