1. Put basmati rice and water in the SS liner of the 6 QT Instant Pot, Take notice of the water level with the measurement markings inside the pressure cooker liner. In a 6 QT it comes up to the 7 cup marking.
2. Take the SS liner to the sink and rinse the rice with more water, pouring off and rinsing again. Stir the rice with a spatula or large spoon while rinsing to free up the rice dust and husks that need to be rinsed away. Lastly, refill with fresh water up to the level you noted earlier, a 6 qt liner = the 7 cup marking.
3. Close the lid on the pressure cooker, set the valve to "sealing" and start the pressure cooker on High for 4 minutes. Once completed, leave the pressure cooker on sealing for another 10 minutes before quick-releasing the remaining pressure.
4. Divide into flat stackable containers or your preferred size of Souper Cubes and freeze for future use.
