Step 1

Heat the milk in a large covered pot over high heat until it reaches between 180-200 degrees Fahrenheit. This usually takes 12-15 minutes. Keep an eye on it so it doesn't boil over.

Step 2

Place the pot in the sink and fill the sink with cold water along with some ice or a few ice packs you'd use in your kid's lunch kit. Cool the milk until it reaches 100-110 degrees Fahrenheit, which should take about 15-20 minutes.

Step 3

Transfer the cooled milk to the Instant Pot liner along with the 1/4 cup of plain, starter yogurt. Be careful not to scrape the bottom of the pot, as it will likely have formed a brown crust.

Step 4

Cover with a regular pot lid and set it on the yogurt function for 8-12 hours.

Step 5

Scoop your yogurt into clean glass jars and store in the fridge for up to two weeks.
