Preheat oven to 400 °F. Rub pork with liquid smoke, salt, and
ginger. Cover meat with onion slices. Wrap pork in foil and seal
completely. Wrap with wet paper towels (or banana leaves) and seal
with another layer of foil. Place pork in roasting pan and bake
for at least 5 hours, reducing heat to 250 °F after the first hour.
After baking, shred pork, and season with additional Hawaiian salt
if necessary. Makes 10 servings.
