Understanding Pressure Cooking
Pressure cooking is a method of cooking that uses high pressure, typically achieved by sealing the cooking vessel (pressure cooker) and allowing the steam to build up, increasing the internal pressure. This elevated pressure is what allows for faster cooking times compared to conventional cooking methods. The basic principle behind pressure cooking is that higher pressures result in higher boiling points of water. Since water boils at 100°C (212°F) at sea level, increasing the pressure allows water to reach temperatures above 100°C, which in turn speeds up the cooking process.
The Science of Cooking Meat
Cooking meat involves breaking down its fibers and connective tissues to make it tender and palatable. This process is primarily influenced by heat, moisture, and time. Meat consists of proteins, fats, and connective tissues like collagen. When heated, proteins denature (unfold), fats melt, and collagen dissolves into gelatin, making the meat tender. The application of heat and moisture in a controlled environment, such as a pressure cooker, significantly accelerates this process.
