I see there's talk here of making stock. I use the instapot succesfully and can make stock in a few hours that's like jello - I'll follow up later with some instructions if anyone finds it helpful. Keeps the smell down too - not that i mind it

Here is slow mo of chicken and duck feet stock. spoon stands straight up in it after cooling and prior to skimming fat. Fun stuff!
