In a food processor or blender, combine all of the ingredients except for the pork shoulder and pulse until everything is finely chopped. If you do not have a food processor or blender, just finely chop the herbs and mince the garlic, then combine everything in a bowl and whisk together. Set aside about 1/3 cup of the mojo sauce for later and keep it in the fridge while the pork cooks.
