Pressure cooking is a cooking technique in which food is cooked in a sealed pot under pressure and high temperatures, allowing it to cook faster than traditional cooking methods.
The pressure cooker is designed to trap steam generated from the boiling liquid inside, which raises the internal pressure and temperature. This increased pressure and temperature allows food to cook more quickly and evenly, often in a fraction of the time it would take using conventional cooking methods.
Pressure cooking is commonly used for cooking meats, grains, legumes, and vegetables. It can help to preserve the nutritional value of food, as well as enhance the flavor and texture. Pressure cookers come in a variety of sizes and can be electric or stovetop models.

When pressure cooking at different altitudes, adjustments may need to be made to account for the changes in air pressure. Here are some general guidelines for pressure cooking at different altitudes:
- At high altitudes (above 3,000 feet or 914 meters), the boiling point of water decreases, which can affect the cooking time and temperature of food. To adjust for this, you may need to increase the cooking time or pressure when pressure cooking at higher elevations.
- For every 1,000 feet (305 meters) above sea level, you may need to increase the cooking time by 5% to 10%, depending on the recipe and the altitude. Consult the manufacturer's instructions for your pressure cooker for specific guidelines on adjusting cooking times and pressure at high altitudes.
- When pressure cooking at high altitudes, it is important to follow all safety guidelines for pressure cooking, including using a reliable and properly calibrated pressure cooker, using the correct amount of liquid, and releasing pressure safely and carefully.
- It is also important to use caution when opening the pressure cooker at high altitudes, as the decreased air pressure can cause the contents to boil vigorously and potentially splash or spew out of the pot. Wait for the pressure to release completely before opening the lid and use caution when removing food from the pot.
