To master the heat of the chicken stew in the pressure cooker, generally turn on the medium heat first, and when the valve on the pot cover comes up and the gas rushes out, turn down the heat (very small) and then add the high-pressure valve.
The time for stewing chicken in pressure cooker is mainly 15 to 25 minutes, but the specific cooking time depends on whether you like it soft or hard.
When the valve on the cover falls off, you turn the high-pressure valve around, which means it can be opened without ventilation. If you can't wait, flush the lid with cold water, and you can open it when you hear the sound of the valve falling on the lid.
