Place the rice and water into a rice cooker. Cook the rice according to the “white rice” setting on the rice cooker.
When the rice has finished cooking, evenly pour the seasoned rice vinegar all over the rice. Toss the rice around to further distribute the rice vinegar, taking care to be gentle, and not mash the rice.
I don’t wash the rice before cooking. I know some people are adamant about washing the rice beforehand, but the brand I use specifies to combine the rice with the water as is. You can wash the rice if you prefer.
