Add 1 cup of water into the instant pot insert. Place the trivet and then arrange 4 ears of full corn (as pictured). You can also break ears of corn in halves.
Close the Instant Pot with pressure valve to Sealing. Cook on High Pressure for 2 minutes.
Once the instant pot beeps, Do a Quick Release.
Use kitchen tongs to remove the hot ears of corn from the pot. Serve warm with butter, salt, pepper, and lime juice.
