Marinade the pork in all of the other ingredients other than the wood chips (obviously)
Soak wood chips in water for a hour.
Set up charcoal grill with a hot and cool side.
Heat grill so hot side is very hot, then add your wood chips, it should get very smokey.
Then add your pork to the cool side of the grill. Close the lid and the vents. Cook for 3 to 4 hours. By the end of the cooking process the meat should be extremely tender.
Now pull apart the meat and add it to a skillet. Pour the broth over the meat and cook for another 20 minutes. Allow some of the broth to evaporate and stir the meat together so it absorbs the broth.
Serve with a warm tortilla and your favorite taco accessories.
Enjoy!
