Make a few slits halfway through the pork roast. Pat the garlic mixture into the cuts. Place the roast in the bottom of your crock pot.
Mix bourbon, cider, molasses and brown sugar. Heat slightly to dissolve the molasses and brown sugar in the liquid. Pour the bourbon mixture into the crock pot with the meat.
Cover the crock pot and cook on low for 7-8 hours.
Remove the pork from the crock pot and shred with two forks. (If you would like, you can skim the fat off of the top of the juice left in the crock pot. Discard the fat.)
Return the pulled pork to the juices in the crock pot and cook on low for 1-2 hours, uncovered (to thicken the sauce and continue to flavor the meat). *
Serve pork on a sourdough slider bun.
Notes
*If you prefer your pork a bit sweeter, mix an extra 1 tablespoon of brown sugar into the pulled pork before serving.
