Sealing in Steam and Heat
When you place the lid on a pressure cooker and secure it tightly, it creates an airtight seal. This seal prevents steam from escaping, allowing the pressure to build up inside the pot. As the liquid inside heats up, it starts to boil and generate steam. The trapped steam increases the pressure inside the pot rapidly, cooking the food faster.
Regulating Pressure
A pressure cooker has a valve or pressure regulator that helps maintain a specific pressure level inside the pot. The valve can be adjusted to control the amount of pressure that builds up. When the pressure reaches the desired level, the valve releases excess steam, preventing the pressure from getting too high. This safety feature ensures that the pressure cooker does not explode due to excessive pressure.
