Once the Instant Pot gets hot, place the pork whole into the instant pot. Sear all the sides of the pork for 3-5 minutes each side.
Once seared. Remove the pork and set aside. Add the water and cancel the instant pot setting. Using a wooden spatula, scrape any seared meat remnants to prevent a burn notice.
Add the liquid smoke and return the pork to the instant pot. Salt the top of the pork.
Seal the lid and pressure valve. Set the instant pot to 90 minutes on high pressure.
Once finished, let the Instant Pot have a natural release pressure for 15 minutes then manually release.
Remove the pork from the Instant Pot onto a cutting board. Using some forks shred the pork. Add the shredded pork to a plate for serving.
Serve pork with steamed rice and peppers and pineapple.
Notes
