The Basics of Pressure Cooking
Before diving into the fears surrounding pressure cookers, it’s essential to understand how they work. A pressure cooker operates by creating a sealed environment that traps steam and raises the internal pressure. This trapped steam increases the boiling point of water, allowing food to cook faster than traditional methods.
How Pressure Cookers Work
When heated, a pressure cooker increases the temperature within its sealed environment. Here’s how the process unfolds:
- Sealing: The lid locks into place, creating an airtight chamber.
- Heating: Once the cooker is heated, water inside begins to boil, creating steam.
- Increased Pressure: As steam builds up inside, pressure increases, allowing the temperature to rise above 100°C (212°F).
- Cooking: The high temperature cooks food more quickly and evenly.
The Science Behind Pressure Cooking
The science is straightforward yet fascinating. Pressure cooking is based on the principles of thermodynamics. The higher pressure not only increases the boiling point of water but also allows food to absorb moisture and flavors, making it incredibly tender and delicious.
