Cooking brown rice perfectly using a rice cooker requires precise measurements of brown rice and water. The ideal brown rice to water ratio for a rice cooker is 1:1.5, meaning for every cup of brown rice, 1.5 cups of water should be used.
Using the correct ratio ensures the rice cooks evenly, resulting in fluffy and flavorful grains. Too little water can leave the rice undercooked and, while too much water can make it mushy and sticky. Additionally, factors like the type of rice cooker, altitude, and personal preference can slightly affect the optimal ratio.
