Step 1

Add milk to a 6-qt Instant Pot®; close and lock the lid. Select yogurt setting; adjust pressure to boil. This can take up to 1 hour.

Step 2

Working carefully, cool the Instant Pot® insert in a bowl of ice water, stirring occasionally, until the milk reaches 100 to 110 degrees F, about 15- 20 minutes; set aside 1 cup milk.

Step 3

In a medium bowl, whisk together yogurt and reserved 1 cup milk. Stir into remaining milk, being careful not to scrape the bottom of the insert.

Step 4

Return insert into the Instant Pot®. Select yogurt setting, set automatically at 8 hours.

Step 5

Transfer to storage containers; cover and chill until cold, about 6-8 hours, or up to 10 days.
