A rice cooker is a kitchen appliance designed to automate the cooking of rice. It typically consists of a heating element, a cooking pot, and a lid. When water and rice are added, the cooker heats the water until it boils, then maintains the temperature to steam the rice until it is fully cooked. Most rice cookers have an automatic shut-off feature that activates when the water has been absorbed. In addition to cooking rice, many rice cookers can also prepare other grains, such as quinoa and barley, and some models include settings for steaming vegetables or cooking soups. They are popular for their convenience and ability to produce consistent results, making them a valuable tool in many kitchens.
