Homemade Yogurt has NEVER been easier than with this Cold Start Instant Pot Yogurt. Two ingredients and time is all you need to have perfect, creamy, thick yogurt.
Whisk 1 cup of milk with 2 tablespoons prepared yogurt with live cultures (or starter) until well combined.
Pour the remaining amount of 52 ounces Ultra Pasteurized Milk into the inner pot of pressure cooker and then whisk in starter mixture.
Place lid on the pressure cooker. There is no need to seal.
To set the incubation time, hit yogurt function and then adjust function until the time reads 8:00 (be sure pressure is at normal and not low--if at low hit yogurt again.) *See recipe notes on using a Duo Plus Model.
After the 8 hour incubation period, remove inner pot from pressure cooker. Cover with plastic wrap and place in refrigerator for 8 hours.
After refrigeration, store yogurt in glass containers for 10-14 days.

Notes
Fairlife milk is also ultra-filtered, which means it has more protein and less sugar, meaning it will produce a thicker yogurt than just ultra-pasteurized milk. If you use ultra-pasteurized milk, not ultra-filtered milk, you may want to strain your yogurt for super thick yogurt. Ultra-filtered vs Ultra-pasteurized: Ultra-filtered milk does seem to be more foolproof than ultra-pasteurized milk--as a couple of brands have not set up as well for readers. For Custom Temp: If you have an Instant Pot Evo Duo Plus, select custom temperature using the yogurt function and set to 110 degrees. For a Duo Plus, hit Yogurt than hit the down button on temperature, so the screen reads "8:00" medium. That will skip the boil sectionThe nutrition was calculated using 2% milk and each serving size is 4 ounces.
