Rinse the rice 2-3 times, until the water runs clear. Drain and keep aside.
Pressure Cook ONE of Two Ways:
Main Pot: Turn on the Instant Pot. Add rinsed rice, water, salt and oil (if using). Close the lid and set the vent to sealing mode. Pressure cook for 5 minutes at high pressure on Pressure cook or Manual mode.
Pot-in-Pot Method: Assemble the rinsed rice, water, salt and olive oil (if using) in an oven-safe bowl that fits easily in your Instant Pot. Depending on the size of your pot, add 1-2 cups of water in the inner pot. Place a trivet. Place the rice bowl on top of that. Close the lid and pressure cook for 5 minutes at high pressure, sealing mode.
Release Pressure and Fluff Rice
Once cooking time is up, let the pressure release naturally for 5 minutes. Release the remaining pressure by following the quick release instructions of your model. Open the lid after the pin drops.Using a fork, gently fluff the rice. No stirring. Then, let the rice rest for 5 minutes, uncovered. This evaporates any excess moisture and the end result is fluffier.
Notes
Rinse Well: Rinsing removes the excess starch coating on rice and makes the end result very light and fluffy. A fine mesh strainer is a great tool.
Liquid to Rice Ratio: The water-to-rice ratio is way different in the Instant Pot as compared to the stove-top recipe. I follow a ratio of 1 cup rice to 1 cup water.
Rice Setting: In my test runs, results were exactly the same when cooking rice at High pressure for 5 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.
Pot-in-Pot Method: Add 1-2 cups of water to 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.
Fluff and Rest: 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.
