Ancient ways of cooking rice:

People are eating rice for ages even when the rice cooker was not invented people also made rice for their healthy living. It was a laborious task to make rice without the rice cooker.

People made rice by placing a heavy earthenware pot on the burning woods and make rice in that heavy pot by boiling and steaming, by applying different methods. This process requires a lot of energy, time, and experience to make rice.

Modern rice cooker:

With the evaluations in the rice cooker from the heavy earthenware pots, we came along to the lightweight durable and even portable rice cooker in the market. It is a small and smart appliance heaving the main body with a cooking pot inside, and a thermostat that controls the temperature and has a heating element to transfer heat to the rice required for cooking.

Types of rice cookers:

There are two types of rice found in the market. That is the difference is in their connectivity.

These two types are

Electrical rice cooker; this type of rice cooker works with the fluctuating magnetic field that fluctuates around the cell. This fluctuating magnetic field creates current around the boiling pot which produces quicker heat.

Gas rice cooker; the gas rice cookers have significantly greater demand in the market than the electrical gas cooker. This type of rice cooker doesn’t come with an electrical power source but has to fuel gas source from the external ways for its working.

It May did not turn off; besides having the automatic turn-off feature the cooker may not turn off due to some functional disabilities. This can overcook or even burn the rice too. 

Nonstick feature; in the rice cookers, the boiling pot is made of non-stick material which means that you have to be careful while scooping the rice out. If you scooped the rice with the metal utensil it may cause damage to the nonstick layer on the pot and afterward, you will face a bad cooking experience. And sometimes a little strange taste in the rice too.

Bottom burned rice; the bottom layer of the rice will get burned. It is good to stir the rice in the cooker every 2-3 minutes so that the bottoms will never get burned. You will have the perfectly cooked rice on your plate.
