Begin by thoroughly washing the Sona Masoori rice and then draining it.
Transfer the drained rice into the inner pot of your Instant Pot.
Pour in 2.5 cups of water over the rice.
Secure the lid on the Instant Pot, ensuring that the valve is set to the SEALED position.
Choose the PRESSURE COOKER or MANUAL setting, set it to HIGH pressure, and cook for 12 minutes.
Once the cooking cycle is complete and the Instant Pot signals with a beep, allow the pressure to release naturally for 10 minutes.
After the natural release, perform a Quick Release to let out any remaining steam.
Open the lid carefully, then gently fluff the rice with a fork.
Serve the rice hot and enjoy.
