In the Instant Pot cooking pot, whisk together cold milk and yogurt.
Cover*, push yogurt button and set time to 8 hours**. Setting should be Normal setting (not low or high).
After 8 hours, carefully place cooking pot in fridge and refrigerate overnight. Serve!
Notes
*Can use any cover, doesn’t need to be pressurized so the locking lid isn't necessary (but can be used).**For a more tart or sour yogurt, set time for up to 10 hours.Recipe can easily be doubled, or scaled for your container of milk.The yogurt will keep for 2 weeks in the refrigerator. Store in mason jars, or another air tight container.Save a Tablespoon or two of yogurt for your next batch! I recommend using the same starter only 2-3 times and then buying a new starter to keep the yogurt thick and the best texture.For a greek style yogurt, strain using cheesecloth.
