Rinse rice. I prefer using a sieve to rinse the rice. Flow cool running water through the rice and scrub with your fingers until the water runs clear. If you don't have a sieve, you can scrub the rice and water in a bowl with your fingers, pour out the milky water, and repeat rinsing until the water is clear.
Load the Pressure Cooker. Put the rinsed rice, water, and salt in a small metal bowl. Make sure you are able to reach your fingers around the bowl to pick it up out of the Instant Pot, otherwise select a smaller bowl size. Fill your Instant Pot with around 1-cm depth of water. Put the small metal bowl into the Instant Pot.
Pressure Cook the white rice. Pressure Cook the white rice on High for 3 minutes, with 10 minutes of Natural Release. If you are doubling the recipe (2 cups white rice and 2 cups of water), then Pressure Cook on High for 5 minutes, with 10 minutes of Natural Release. Quick Release any remaining pressure.
Add optional toppings and serve. Fluff up your white rice with a fork or rice paddle. Sprinkle on furikake rice seasoning over the rice if desired. Serve immediately.
