A pressure cooker is a type of "smart" pots, which are much easier long and laborious cooking process. It allows several times to reduce the cooking time and turn the most stringent food in delicate dishes. It is possible to prepare soups, side dishes, meat and desserts. The sealed pan limits contact with the air and reduces the process of oxidation products, thereby maintaining maximum vitamins, aroma, color and flavor in the finished dish.
The first pressure cooker was invented back in the XVII century, they have been successfully used by our ancestors. Despite the fact that modern devices have stepped far forward, many people avoid cooking them, perhaps because of the problems that can occur if used improperly. Do not worry - in the current models of safety comes first, we just need to learn some simple precautions. The operating principle of the pressure cooker is preserved in spite of the many changes.

Modern device is a special pan with a lid and hermetically sealed valves that regulate the pressure within. When heated, steam is generated, which goes out of the sealed container and the internal pressure increases, whereby the reflux temperature rises to about 120 degrees. This allows you to prepare food faster.
At the maximum pressure valves are activated, which provide relief steam. Typically, the device is equipped with operating and safety valve. In addition to devices designed for use on a normal plate, released, and standalone electric pressure cooker, equipped with heating elements and the control panel.
How to use a pressure cooker
Put all ingredients in a saucepan and mix thoroughly, you need to tightly close the lid and put on a plate. Cooking time is necessary to count from the moment of boiling liquid. This will prompt the steam exiting the valves or special sensors. Heating under the pot must necessarily be reduced.
Important! It is not necessary to cook at too high a temperature. It does not speed up the cooking process and only leads to an overload of the apparatus.
At the end of the process you need to turn off the heat and let the steam out of the pan without opening the lid. To do this, set the valve to the desired position, a first for the slow releasing, then fast. The steam outlet can take from 5 to 20 minutes.
For quenching can be directed to cover the jet of cold water, avoiding contact with the valves. He continues to prepare the dish, while the pressure is maintained in the pan. After using the cooker should be thoroughly washed, especially the rim and the gasket on the cover to subsequently stuck residues not broken the seal.
Attention! Since the degree of readiness can not be verified in the process, it is recommended to calculate the cooking time and use the recipes for pressure cookers. It should also be borne in mind that the liquid has almost boils, and it takes less than for a conventional pan.
What not to do
If you forget about safety precautions, food preparation process can result in unpleasant surprises, since the principle of the pressure cooker works associated with the formation of steam and high pressure inside the pot. You need to remember the simple rules:
-
The pan must necessarily be liquid, its minimum number - about 0.5 liters. - Container can not be filled by more than 2/3, the remaining space is filled with steam. Usually on the pan has a label for maximum volume.
- Do not open the cover if the valve continues to produce steam. Use caution when opening to avoid burns by steam, even if it ceased publication.
- You should not cook foods that cause excessive foaming (some types of cereals, fruits, vegetables), because it may clog the valve. Broth better boil and a lid with a conventional pre remove foam.
- You can not use a pressure cooker, in which there are defects and cracks, including the rubber cushions.
- It is not recommended to store and cook in a pressure cooker to cook, it should shift into another bowl.
Currently, the well-known brands of household appliances produced Multivarki a function of pressure cookers. Such devices can be excellent assistants to any kitchen.
