How does the water circulate in an Instant Pot?
Discussion
By convection primarily but because it’s not boiling you don’t risk the bottom burning typically. However if you’re cooking a very thick liquid like tomato sauce I recommend getting it to a boil while stirring first and then covering it for pressure cooking to avoid burning bottom.
I mean when covered and using the pressure cooking aspect it doesn’t boil. It’ll obviously boil if uncovered.
I don't think it does. Just keeps it at the set temperature.
