. pressure cooking is a process of cooking in a special utensil which allows cooking with a lot of steam under pressure. pressure cookers are made of steel or from a mixture of aluminium and other metals and can with stand high pressure. the steam produced is trapped inside the cooker thus increasing the pressure and temprature above 100.c rice pulses meat potatoes roots beans and peas are cooked well in a pressure cooker in the shortest possible time.

. it is important to remember that once the pressure cooker develops optimum pressure the excess steam is release through the weight kept on its lid. one should lower the flame under the pressure cooker at this time. this maintains the pressure and avoids fuel wastage. we must also remember to clean the weight regularly as it has tiny holes which get blocked with food. this prevents the escape of exeess steam built up in the pressure cooker which can lead to the bursting of the pressure cooker and causing severe injuries you must also check the rubber gasket of the pressure cooker as it creates useal because of which steam is trapped.

Advantages:pressure cooking kills all bacteria and hence the food is safe and hygienic to eat. the food gets cooked faster l.e. almost in 1/3rd time than boiling. this also saves the fuel. several foods can be cooked together in the pressure cooker by using separator. it is not necessary to immerce food in water while cooking and this reduces the loss of water soluble. vitamins and minerals

disadvantage:if food is cooked for very long it losses its texture and may even burn.
