Don't have a smoker but love pulled pork? That's ok, pulled pork made in an Instant Pot can be great too
Cut the pork shoulder into large chunks - approximately 2 inch cubes, trimming and discarding any of the thick fat cap
Turn the Instant Pot onto sauté mode, and add the oil to the pot
When oil is hot, brown the pieces of pork until browned on each side. You may have to work in batches if you are using a large piece of pork
Remove all pieces of pork, and pour in the cup of beer and bourbon and scrape up any browned bits from the bottom of the pot, then put pork back in the pot and add the liquid smoke
Close the lid and seal the vent, and pressure cook on high pressure for 60 minutes. After pressure cooking, allow to naturally pressure release for 20 minutes, then release any remaining pressure
Pull the pork apart with two forks, mix in barbecue sauce, and serve
