A rice cooker is a small electric appliance designed to boil rice perfectly with minimal attention. The cook adds rinsed rice and a measured amount of water, switches on, and the cooker’s thermostat holds a boil until the water is absorbed, then detects the temperature rise that signals the rice is done and switches to a warming mode. The result is evenly cooked grains without sticking, burning, or boil-over, and the keep-warm function holds rice safely for serving. Basic models handle white rice; fuzzy-logic versions adjust time and temperature for brown rice, porridge, and steaming. In much of Asia the rice cooker is as fundamental as the kettle, a set-and-forget tool that freed cooks from watching the pot.
