What is a pressure cooker and how does it work?
A pressure cooker is a kitchen appliance that cooks food quickly under high pressure. It operates by trapping steam inside a sealed pot, which raises the internal temperature above the boiling point of water. This process enables food to cook faster than conventional methods, retaining moisture, nutrients, and flavors.
The cooker uses a locking lid that creates an airtight seal, allowing pressure to build up as the liquid inside heats. Most modern pressure cookers have built-in safety features that prevent excessive pressure buildup, ensuring safe operation. They can be stovetop or electric models, each with its specifications and methods of sealing.
How do I know if my pressure cooker is sealed properly?
To ensure your pressure cooker is sealed properly, check that the lid is locked in place according to the manufacturer’s instructions. Most pressure cookers have visual indicators, such as a pressure indicator or a locking mechanism, to confirm that the lid is securely closed.
Additionally, listen for the sound of steam escaping. If you hear steam hissing or see steam escaping from the sides, it may indicate that the seal is not functioning correctly. Double-check the gasket and the sealing rim for damage or food debris, as these can prevent a proper seal.
