The Basics of Pressure Cooking
Before diving into the specifics about plastics, it’s essential to grasp the concept of pressure cooking.
What is Pressure Cooking?
Pressure cooking is a cooking technique that uses steam and high pressure to cook food. The pressure raises the boiling point of water, allowing food to cook faster than conventional methods. By sealing food in a pot and heating it, steam builds up, leading to higher temperatures and shorter cooking times.
Materials Commonly Used in Pressure Cookers
Pressure cookers are typically constructed from materials that can withstand high temperatures and pressures, including:
- Stainless Steel: Known for its durability and resistance to rust and corrosion. Stainless steel pressure cookers are favored for their ability to distribute heat evenly.
- Aluminum: Lightweight and excellent at conducting heat, but can warp over time if subjected to high temperatures.
Knowing these materials helps clarify why certain items, particularly plastics, may not be suitable for a pressure cooker.
The Issue with Plastic in Pressure Cookers
Plastics are ubiquitous in the kitchen, from food storage containers to utensils. However, pressure cooking presents unique challenges for plastic materials.
Why You Should Avoid Plastic
