In a 6qt Instant Pot dunk in both the bottles of milk.
Mix in the whole of yogurt. Ensure that you have a clean and fresh lid, seal and insert pot or you could end up with yogurt smelling like the gravy you previously cooked before!
Now close the IP lid. I have an Ultra model. Now, in ultra, go to Yogurt mode, set in a time about 8 hours and custom the dial to read a 110F in the screen. Then press start.
For other models, press the yogurt button and set it to normal for 8 hours or more.
Once done, open the lid and transfer to the fridge. Cool it at least for 4 hours to get the perfect yogurt.
Note: Milk used here is ultra-filtered. This is why it is not boiled. This is cold starter method. For other milks, kindly boil milk to a 180F, cool it to 110F or room temperature. Then you can continue to pour that milk in IP and follow the remaining steps.
