Instant Pot Cooking:Cooking for Zero minutes can sound strange but remember the ingredients will begin cooking as soon as the time is set. The lower element will begin heating up to boil the liquid to create steam. The steam will create pressure and seal the pressure cooker closed.Once the Instant Pot has reached pressure the button will sound let you know the timer has begun. Then another alarm will sound letting you know the cooking process is complete.This is the perfect amount of time to pressure cook meatballs
