I do about 11 to 12 hours in the Instant Pot (Duo 6)
I shake the carton well, pour some out in a clean 7 cup Pyrex bowl. This leaves room for the foam created by shaking.
I then add one probiotic cap contents to the carton and shake very well, and add to the bowl.
Set directly in bottom of the IP pot. Use a plate to cover the top
Select yogurt button, being sure it's on the yogurt setting,not the low or the boil
I leave it for more time than I want because it counts up, that way I know how long it's been going
Let it sit without disturbing the contents to cool in fridge. Do not stir or spoon before it's chilled or it seperates a lot
I've actually had better success with individual jars, because every time you spoon some out it seperates a bit, but I like the bowl because I use one cup right off for cheese, then I strain in a wire mesh lined with paper towel
