Make Sauce a day ahead and refrigerate until ready for use
Put all sauce ingredients in food processor and blend until smooth.
Rub Pork with salt, add next 4 ingredients and place in crock pot for 6-8 hours. I have a hi-lo setting on my crockpot that automatically kicks from hi to lo after 2 hours. If yours does not just use lo for the full 8 hours.
When pork is cooked remove from crock pot and shred, dump all fat and liquid from crock pot and return shredded pork.
Pour raw Sauce in crock pot and cook on high for 2-3 more hours.
