Notes
Pork: For this recipe, you'll want a fattier cut of pork, like a pork butt (Boston butt).
Liquid smoke: Liquid smoke is a flavoring that's usually sold either near the barbecue sauce or with marinades. Any flavor of liquid smoke will work.
Sea salt: Hawaiian sea salt (alaea salt) is preferable. However, if you can't find that, pink Himalayan salt makes a good substitute. White sea salt will also work in this recipe. Just be sure that you don't use table salt as it will be overly salty.
