Sterilze the Instant Pot container by adding 2 cups of water, place the top on and set it to steam it for about 3 minutes.
Pour out the water.
Add the milk to the container and with the top off of the instant Pot, boil it by using a "Boil" setting or a "Saute" setting. Use a thermometer to measure when the milk reaches 180℉ and then turn it off and let it cool to 80 to 90℉.
Add your yogurt starter to the milk and place the top on the Instant Pot.
Press the yogurt button and set the time for 24 hours.
