Measure the rice. Measure the rice with a traditional measuring cup and add it to the rice cooker pot.
Wash the rice. Rinse the rice using cold tap water. Use your hand to move the rice around and clean the grains. Pour out the white water and repeat 3-4 times or until the water is mostly clear. You can also wash the rice in a fine mesh sieve. Be sure to drain the water completely.
Cook the rice. Add the filtered water and salt if using, then place the rice in the rice cooker, close the lid, and hit start or cook according to your rice cooker’s manual instructions. If your rice cooker has a sweet rice function, use that. Do not lift the lid until the rice is done cooking.
Fluff and serve. The rice cooker will notify you when the rice is done. Open the lid and fluff the rice with a rice spatula. Be careful, the steam will vent out quickly. Serve immediately.
