Optional: rinse rice until the water is clear. I like to do this like they do in the Japanese restaurant videos on YouTube: swish in a strainer in a big bowl of water, and change out the water a couple of time. The agitation and not-just-letting-the-water-run aspects make me feel better about it. I have no idea if it is more effective or a better use of water or what. Let it dry for a few minutes in the strainer.
Add the rice and measured water to Instant Pot and use rice setting - low pressure for 12 minutes. Once done, follow natural release method - allow about 10 minutes before degassing.
Meanwhile, in a small bowl - combine white vinegar, rice vinegar, salt, and sugar. Maybe microwave for 1 minute, maybe not, then stir until completely dissolved.
Transfer rice to a large bowl, add vinegar mixture and gently mix well to combine.
Let it cool some or all the way. Use in your favorite ways. Enjoy!
