1 gallon whole milk
1 c plain yogurt
Pour milk into Instant Pot. Push Yogurt button until it says boil. Put a lid on (glass lid ok). When it beeps (temp at 180), turn it off, take the liner out, and cool in an ice bath to 120-125 (110 on small instant read meat thermometer, 120 on small black instant read, 117 on blue lab thermometer) (or just let cool). Stir in starter. Return to Instant Pot and push Yogurt button until says 8:00. When done, set aside 1 cup as starter for next time.
