Mix a little of the Fairlife milk with the starter yogurt until smooth. You can do this in a small bowl, or right in your Instant Pot.
If using a small bowl, pour the mixture into your Instant Pot along with the rest of the milk.
Add the sweetened condensed milk (if using), and whisk all ingredients together until mixed well. It will be foamy.
You can either place the Instant Pot lid, or a regular pot lid that fits on the Instant Pot. We are not pressure cooking, so you don't need to worry about sealing the valve.
Press the "Yogurt" button on your Instant Pot. It should automatically set itself to 8 hours. You can add more time if you'd like, just remember the longer you set it for, the more tart it will taste.
I always set mine for the 8 hours and it turns out great!
Once it's done, lift the lid and place a papertowel over the pot. Put the lid back on, and place the pot into the refrigerator to cool and set overnight.
The next morning, the yogurt will be ready to dip and serve.
Serve with your favorite fruit, granola, and/or honey.
Be sure to reserve 2 heaping Tablespoons of your fresh yogurt to use in your next batch (see notes).
