If you have an Instantpot, you just add a half gallon of milk and use the “boil” setting on the yogurt function. That brings it up to around 185°. Then you cool that down to 110° (I use a water bath in the sink, which takes less than 5 minutes), stir in some existing active-culture yogurt, set the pot to hold temp for your desired amount of time (10 hours seems to work well), and strain overnight in the fridge to thicken (or not).
I use an insta-pot often, with recipes from this cookbook.
Made a lot of them, some are so-so, some are great.
One of my favorites is the Perfected Cheese Cake.
Yes, cheese cake can be made with a pressure cooker !
Pressure cooker is the easiest and best way to cook corned beef.
Fill just enough water to cover corned beef, add spice packet, set for 2 hours on high.
Advice: If your insta-pot is used a lot or aged, replace sealing o-ring, cheap and on Amazon.
Just be aware there are different sizes of insta-pots.
