With the help of this handy device, you can make nutritious and tasty meals in just minutes. Pressure cooking can save you time and money while allowing you to make all sorts of foods that are nutrient-rich, low in fat, and full of flavor. Although pressure cookers have been around for many years, they have recently grown in popularity thanks to the Instant Pot. But so many of us also have memories of our grandmas cooking meals in their stovetop pressure cookers can you remember the sound of the noisy valve?
Pressure cooking is, at its most basic level, a method of cooking food with steam. The pressure cooker has been around since the s when it was invented by Denis Papin of France. Technology has evolved over the past years and we now have much safer options than the early versions. It works by creating steam pressure in a sealed pot. The steam builds up inside which creates high pressure that helps food to cook faster.
A valve on the top of the pot controls the steam pressure inside. The very high-pressure steam impacts the food inside the pot in two ways:. Choose a pressure cooker that works best for you! With so many types of pressure cookers available today, picking the right one might feel daunting. There are 3 factors to consider when making your purchase:. Also, check out these Instant Pot accessories to find out more about the best ones.
There are two types available: stovetop and electric. When you think of pressure cooking, it could be that the image in your mind is of dodging an exploding pot of green beans in the kitchen. The main thing to do is to find out how your pressure cooker works.
Wondering how to cook with a pressure cooker? Well, find out how to use a pressure cooker in 6 easy steps as follow:.
Add the food and liquid s to the pot. The temperature at which a liquid boils is dependent on the surrounding pressure. When you cook in a regular pot at atmospheric pressure Inside a pressure cooker, the pressure can increase by an additional 15 psi, to almost 30 psi. That means food can cook at a much higher temperature than it ever could at atmospheric pressure—and since cooking reactions speed up at higher temperatures, your food cooks faster.
The same phenomenon explains why cooking at high altitudes can be tricky. Air pressure decreases as you move higher above sea level. At lower pressures, water boils at a lower temperature. At high altitudes, by raising the pressure and boiling point above what happens at sea level, a pressure cooker can really boost the reactions cooking your food.
To put 15 pounds of pressure in perspective, it is less than half the pressure of the air found in car tires, so is not very much; but still, the pressure inside the pressure cooker is still able to significantly shorten the cooking time of food.
The steam pressure inside the pressure cooker cooks food much, much more rapidly than just boiling or baking food. Unlike microwave cooking, pressure-cooked foods become moist and succulent with an intense intermingling of flavours.
Pressure-cooked foods retain much more of their vitamins and nutrients than boiled or commercially processed foods do. Click for Pricing. Problems or suggestions about website: contact. How Pressure Cookers Work. Scientists say climate change is affecting our ability to grow food! The boiling water and steam remain at F, regardless of how long it boils, limiting the rate at which it can cook food.
The only way to increase the temperature of boiling water as it converts to steam is to increase the surrounding pressure. This can be achieved by trapping the steam in an enclosed space. As water transforms into steam, it expands in volume.
If the volume is not allowed to increase, the pressure and therefore temperature , will increase. Pressure cookers trap steam in an enclosed space through an air-tight, locking lid. The longer the water boils, the more the steam pressure builds within the vessel. Pressure cookers have three advantages over oven cooking, the high heat conductivity of steam, the increased temperature from steam pressure, and high energy efficiency. Pressure cookers are a great addition to any kitchen and can make cooking fast, easy, and affordable.
