How does the rice cooker know when the rice is ready?
This is how a basic rice cooker works. At sea level, the boiling temperature for water is 212 degrees F or 100 degrees C. As soon as all the water is absorbed by the rice, the temperature inside the cooker immediately rises. The appliance has a thermostat that detects when the temperature rises above 212 degrees F inside, and turns the heater off.
