Add the rice, water, and 1 teaspoon of salt to a rice cooker.
Cook until the water has been absorbed, then transfer the rice to a large bowl. Most rice cookers have a setting depending on the type of rice you use. For me, I clicked the "White Rice" setting.
Transfer the rice to a bowl and fluff with a fork.
Stir in the chopped cilantro, chopped green onions, lime juice, and lime zest. Add additional salt to taste.
Feel free to rinse the rice before cooking it if you prefer. Rinsing rice removes that excess starch, resulting in grains that are more separate when cooked.
Most rice cookers use the ratio of one cup of rice to one cup of water. Use this same ratio to scale up when cooking larger batches.
When following the rice cooker instructions, make sure to prepare the rice as dictated by your specific variety. You will also need to measure the rice accurately; most rice cookers will come with their own measuring cups.
