Instant Pot. Multi-function cooker (Part 5) in Kitchen Consumer Posted July 28 This may be a dumb question. I was wandering around over at Chowhound and someone's question gave me pause. If I am using the IP to pressure cook and the "Keep Warm" light is on and the timer goes off, does the natural release NOT happen until the unit is turned off? Or does "Keep Warm" and Natural Release happen simultaneously? I never have given it the least thought and I'm not sure now if I usually pressure cook with the "Keep Warm" light on or not. When the timer goes off, I don't touch the IP - I just wait the amount of time indicated for "natural release" and then pop the vent button to finish the release. Am I totally screwing up?
