Place corn on the cob on a trivet inside the Instant Pot.
Pour in 1 cup of water.
Close the lid and make sure the knob is set to SEALING.
Select PRESSURE COOK on HI for 3 minutes. It will take a few minutes for the Instant Pot to come to pressure, then it will count down the minutes while it cooks.
Once the 3 minutes are done, allow for natural release for 2 minutes, then carefully move the knob over to VENT for a quick release.
Once pressure is completely released and the valve has fallen down all the way, carefully turn and open the lid.
Use tongs to remove the corn on the cob and plate.
Notes
Makes 4 corn. You can add up to 6 or even 8 corn on the cob depending on the size of your Instant Pot/electric pressure cooker. If you add more corn, increase the water to 1.5 cups.
