A rice cooker or rice steamer is a container or kitchen appliance dedicated to cooking rice. Electric rice cookers automate the process by mechanically or electronically controlling heat and timing, thus freeing up a heating element on the cooking range that had to be occupied, otherwise for rice cooking. Although the rice cooker does not necessarily speed up the cooking process, with an electric rice cooker the cook’s involvement in cooking rice is reduced to simply measuring the rice, preparing the rice properly and using the correct amount of water. Once the rice cooker is set to cook, the rice will be cooked with no further attention. Many modern cookers have heat insulating casing and a warming mechanism. When the rice is determined to be fully cooked, the unit will automatically switch to the “keep warm” cycle, thus preventing the rice from being overcooked and keeping the rice warm until it is ready to be served.
