Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
Describe how a pressure cooker works

### Response:
A pressure cooker is a sealed pot with a valve that can be used to raise the internal pressure. This allows the water or food inside to be cooked at a much higher temperature than usual, enabling the food to cook faster while retaining more moisture. When the pressure inside the cooker is released, the cooked food can be easily removed.
