The lid of my pressure cooker is stuck. What should I do?
There may still be a buildup of pressure inside. Never attempt to force open the lid of the cooker if there is pressure inside. To check whether there is pressure inside, slightly lift the weight valve and if steam comes out, allow the cooker to cool for some more time. If you used the cold-water-release method, release any remaining pressure and try opening again. If you used the natural release method to de-pressurize the cooker, a slight vacuum may have developed. Heat the pressure cooker over high heat just until steam begins to come out of the pressure regulator valve.
