Rinse the rice in a mesh strainer, until water runs clear, about 2-3 times. If you have the time, soak it for 20-30 minutes. Soaking makes the rice fluffy.
Cooking in the main pot: Add rinsed and drained rice to the pot, along with coconut milk and salt. Close the lid and turn the pressure knob to sealing position. Press Manual or Pressure Cook, for 6 minutes at high pressure. Wait 10 minutes before releasing the pressure manually (NPR 10), after which turn the knob to 'Venting' position. Open the lid after the pin drops. Using a fork, gently fluff the rice.
Cooking rice pot-in-pot (PIP): Combine rinsed and drained rice, coconut milk, and salt in an oven safe container. Pour 1 cup water in the inner pot of Instant Pot. Place a trivet and put the rice container on top of that. Close the lid. Valve set to sealing mode. Cook at Manual or Pressure Cook (High) for 6 minutes. Let the pressure release naturally for 10 minutes before opening the pot (NPR 10). Open lid. Fluff rice with a fork.
Using the RICE Button: You can also cook rice using the RICE button, which defaults to cooking the rice at low pressure for 12 minutes. Follow the same NPR times and process.
Stove-top Recipe
Place a saucepan over high heat. For 1 cup rice, add 1 cup water, 1 cup coconut milk, and salt and, bring the liquid to a boil. Add rinsed and drained rice, stir and reduce the heat to the medium-low. Cover the pot tightly with the lid and cook for 10 minutes.
After 10 minutes, turn off the heat. Open the lid and using a fork, gently fluff the rice. Put the lid back on and let it rest for 5-10 minutes before serving.
Notes
Soak rice: I highly recommend soaking the rice, if you have the time. The grains will be fluffier and more tender.
Follow the ratios as written. The rice to coconut milk to water ratio provides rice that is just the right texture. Not too hard and not too mushy.
Coconut milk choice: For the best flavor, use full-fat coconut milk that is unsweetened.
Stovetop recipe: If making this on the stove, remember to add a cup of water in addition to the coconut milk.
