Pour milk into the inner pot of a the Instant Pot. Close and lock the lid; turn the steam release handle to “Venting.” Press Yogurt, and select “More” mode. (You should see the word “boil” on the display.) Stirring the milk occasionally will help prevent hot spots on the bottom of the pot. When the milk reaches 180°F, the word “yogt” will appear, and the Instant Pot will beep. Stir well, and check that the milk registers at least 180°F, but not more than 185°F on a thermometer. If temperature is less than 180°F, press Yogurt, and repeat the cycle.
