How do high pressure cooker works?Asked on: Oct 27, 2023 12:47 PM
Alright, let's dive into the world of high-pressure cookers! To understand how a high-pressure cooker works, we need to first talk about pressure itself. Pressure is a kind of force applied on a surface. In our case, the 'surface' is the food inside the cooker and the 'force' is applied by steam. When you heat water in an enclosed space (like a pressure cooker), it turns into steam which increases the pressure inside.
Now, why does this matter? Well, under normal circumstances, water boils at 100 degrees Celsius (212 degrees Fahrenheit). But when you increase the pressure, this boiling point also increases. So inside a high-pressure cooker, water can remain liquid at temperatures well above 100 degrees Celsius and get super hot. This super hot water cooks your food faster than if you were just boiling or steaming it at normal atmospheric pressure.
But wait there's more! The high-pressure environment also has another effect on your food. It forces liquid into the food which makes it more juicy and tender. This is particularly great for cooking tough cuts of meat that would normally take hours to become tender.
Now you might be wondering: isn't all this pressure dangerous? The answer is yes, if not handled properly. That's why modern pressure cookers come with safety features like a lock that prevents you from opening the cooker while it's under high pressure and a vent that releases excess steam to prevent an explosion.
In conclusion: High-pressure cookers work by creating an environment where water can get super hot and cook food faster while also making it more tender and juicy. They are safe to use thanks to modern safety features but like any cooking method, they require some practice to master.Reference: Explain that Stuff - Pressure Cookers Reference: The Kitchn - A Primer on Pressure Cooking
