The pressure cooker, once a kitchen mainstay, is reappearing in many modern kitchens because of the easy cooking process it offers to busy cooks. You can use a pressure cooker to safely help you prepare many delicious entrees. After you finish cooking the foods in the pressure cooker, you must allow the pressure to dissipate inside the appliance before easily removing the lid. Sometimes the lid will become stuck on a pressure cooker, however, and you will have to try a few steps to remove it.
Place the pressure cooker back onto the heat source and reheat it until the gauge reaches zero again to release the vacuum created inside the pressure cooker.
Remove the pressure cooker from the heat again and place the pressure cooker into the sink. Run cool water over the lid of the pressure cooker without allowing water to block the vent.
Press down firmly on the center of the lid while turning it to break the seal.
Tap around the entire rim of the pressure cooker lightly with a rubber mallet. Tapping the rim of the appliance may release the vacuum inside the appliance.
Try to remove the lid again by pressing down firmly while turning it. The combination of reheating, cooling and tapping should be enough to break the vacuum.
