Function:
A pressure cooker is a sealed pot with a valve that controls the steam pressure inside. As the pot heats up, the liquid inside forms steam, which raises the pressure and the boiling point of water, allowing food to cook faster and at higher temperatures than conventional methods.
Benefits:
They significantly reduce cooking times, can save energy, and help retain nutrients in food. They are particularly useful for cooking tough cuts of meat, dried beans, or making stocks and sauces quickly.
