Rub butt with garlic, salt and place on banana leaf on top of large sheet of foil. Drizzle liquid smoke and wrap tight with foil. 2 pieces are needed. There are no amounts, everything is done to taste, so experiment. I didn't measure but a good starting point is a tbsp of each ingredient for this 2lb butt.
Bake at 300 deg for 4 hours (large portions of meat will take longer). Then expose the succulent meat and enjoy!
Eat over rice, with cabbage or baby bok choy as I did
