Gather all your sushi rice ingredients.
Pour the sushi rice into a mixing bowl and cover it with water.
Using your fingers, gently swish the rice to clean it.
Tilt the bowl to drain the water, then refill it with fresh water. Repeat rinsing and draining until the water runs clear. You can use a strainer to keep the rice from slipping into the sink.
Let the rinsed rice drain well, or leave it in the strainer for a few minutes until it stops dripping. Next, add the rice and cold water to your Instant Pot.
Lock the lid, set the valve to Sealing, and pressure cook on High for 5 minutes. You can also cook your rice for 12 minutes on Low Pressure.
While the rice cooks, combine the rice vinegar, salt, and sugar until fully dissolved. Microwave for about 1 minute, just until the mixture is warm.
Once the rice is done, let the pressure release naturally for 5 to 10 minutes, then manually release any remaining pressure.
Transfer the Instant Pot rice to a glass bowl and gently spread it out using a rice paddle. A glass bowl helps prevent unwanted flavors and heats up more slowly.
Pour the vinegar mixture over the rice and gently mix until evenly coated.
Let the sushi rice cool slightly, then it is ready to use! Enjoy.
