Pour milk into InstantPot. Screw on the lid and select Yogurt --> Pasteurize. Start the machine.
Allow to heat until timer turns off the InstantPot. Remove lid, then allow to cool on the counter until milk registers 110 degrees F on the thermometer.
Quickly whisk in 1/4 cup of yogurt from a previous batch. Close InstantPot and select Yogurt --> Ferment setting.
Allow to "cook" for 5-12 hours, until yogurt becomes somewhat thick and pulls away from the edges of the pot when you tip it slightly to the side.
Whisk the yogurt to remove any lumps, then pour into a clean canning jar.
Allow jar to sit, covered, on the counter for 2 hours before storing in the fridge. Yogurt keeps at least 2 weeks in the fridge. Be sure to save a 1/4 cup for your next batch! :)
Notes
These instructions don't include reconstituting your starter, which you'll need to do before making yogurt with these instructions. Follow the manufacturer's instructions, as I assume every brand is different. Make sure you're using a thermophilic culture.Recommended Links:
