How to Use a Pressure Cooker

A pressure cooker is a device that allows you to prepare foods such as meats, stews, and vegetables faster than conventional methods such as baking. Basic pressure cookers consist of mainly a large pot with a seal-tight lid. The pressure cooker is placed on a stove with water in it. The seal tight lid allows the temperature of the boiling water to rise to nearly 120 degrees, which is higher than the normal boiling point of water and greatly reduces the time needed to cook. The increase in pressure is ultimately what leads to higher boiling points. In addition, the steam trapped inside the pressure cooker moistens the ingredients, keeping them from burning or drying out.

Modern pressure cookers

We've all heard the horror stories of pressure cookers exploding in people's homes, causing injuries and fires. It is true; the early pressure cookers could be somewhat hazardous if left unattended or used improperly. But pressure cookers have evolved over the years and many of the modern day pressure cookers have features that make them safer and easier to use.

Benefits of pressure cookers

As previously stated, the combination of higher temperatures and retained moisture allows foods to cook much faster. Mathematically, most cooking times can be reduced by a factor of three or four. For instance, green beans can be cooked to perfection in a matter of minutes. Unbelievably, shredded cabbage can be cooked in a minute or less. Medium to small potatoes can be ready in about 5 minutes when cooked in a pressure cooker and a whole chicken – that's right, a whole entire chicken – is ready in 25 minutes or less.

How it works

Built-in safety mechanisms such as the safety valve release steam and pressure when the cooker reaches its preset limits. In addition, many pressure cookers are installed with backup safety mechanisms that allow for quick release of steam and pressure if the initial mechanism fails. Many pressure cooker lids feature a metal plug that will melt and release the pressure if the temperature inside becomes too high.

Other uses

Many mountain climbers tend to use pressure cookers because of the different atmospheric conditions. As explained earlier, water’s boiling point fluctuates according to the amount of pressure exerted on it. The low atmospheric pressure on mountains may cause the water to boil at a much lower temperature, possibly causing food to not be fully cooked.
