Hawaiian alaea sea salt, liquid smoke and garlic are some seasonings commonly used in to make kalua pork. Sea salt is a necessary seasoning, while liquid smoke and garlic are usually optional.
Epicurious.com's recipe for Sam Choy's Oven-Roasted Kalua Pig uses sea salt and liquid smoke as seasoning. To make this recipe, preheat an oven to 350 degrees Fahrenheit. Cut 1/4 inch deep slits in the top of the pork roast. Rub 2 tablespoons of coarse Hawaiian sea salt over the surface of the roast. Wrap the roast in three banana leaves until completely covered, and secure with kitchen string.
Place the wrapped pork in a roasting pan, and add 4 cups water. Bake for about five hours, unwrap the pork and use a fork to shred the meat. Place the shredded pork in a bowl. In a pan, bring 2 cups water, 1/2 teaspoon liquid smoke and 2 teaspoons sea salt to a boil. Pour the mixture over the pork. Stir to coat, and let the pork sit for about 10 minutes before serving.
NomNomPaleo.com's recipe for Slow Cooker Kalua Pork uses garlic and bacon in addition to sea salt. In this recipe, the pork is cooked with bacon and garlic cloves in a slow cooker. Remove the pork from the slow cooker or pan before shredding to avoid overly salty meat.
