Soak the rice in about 2 cups of water, for 15 minutes. Soaking the rice makes them softer after cooking. I prefer to do this step for all kinds of long grain white rice. After 15 mins, rinse the rice 2-3 times, until the water runs clear. This removes any excess starch in rice, and makes them fluffy.
Turn on the Instant pot. Add rinsed rice, water, salt and oil. Close lid. Set vent to sealing position in DUO model. Pressure cook for 6 mins on Pressure cook or Manual mode. Alternatively, you can press the 'RICE' mode, which cooks at Low pressure, for 12 mins.
Once cooking time is up, let the pressure release naturally for 5-10 mins. Release the remaining pressure by turning the vent to 'Venting' position in DUO, or, push down the pressure valve in ULTRA. Open lid after the pin drops. Using a fork, gently fluff the rice.
Tips for Making Perfect Rice in an Instant Pot
If using a long grain variety, I find that soaking rice for 15 minutes removes excess starch and makes the end result very light and fluffy.
The water-to-rice ratio is way different in the Instant Pot as compared to the stove-top recipe. Using the customizing tips above, use one of the following three ratios: 1:1, 1: 1.25, 1:1.125.
In my test runs, results were exactly the same when cooking rice at high pressure for 6 mins, or, on the Rice mode. So, pick a mode based on your convenience.
NPR or QR? For best results, I let the pressure release naturally for 5-10 minutes, after which I manually release the remaining pressure.
When making rice using the Pot-in-Pot method, add 1-2 cups water in the inner pot based on the size of your pot. For 3 qt and 6qt, add 1 cup. For 8qt, add 2 cups. Please remember: you still have to add water to the rice bowl as per the recipe instructions.
After opening the lid, using a fork, gently fluff the rice. No stirring. Then, let the rice rest for 5 mins, uncovered. This evaporates any excess moisture and the end result is fluffier.
