Pour the water into a small saucepan and bring it to a rolling boil over medium-high heat. Once the water reaches a vigorous boil, add the black rice, stirring briefly to ensure even distribution. Allow the rice to cook uncovered for approximately 16 minutes, during which most of the liquid will gradually absorb.

After the cooking time has elapsed, turn off the heat and immediately cover the saucepan with a lid. Let the rice sit undisturbed for about 5 minutes, allowing any remaining moisture to be absorbed and the grains to reach a tender yet slightly chewy texture. Fluff with a fork before serving.
