Add the pork shoulder to the marinade and massage it into the meat. Cover and refrigerate for 4 hours or overnight for best results.
Preheat a grill or grill pan over medium high heat. Remove the pork from the marinade, shaking off excess liquid. Grill the pork until cooked through and lightly charred, about 5 minutes per side.
Allow the pork to rest for 10 minutes before shredding it with two forks.
