In a small mixing bowl stir together the peach preserves, Whiskey, and minced garlic. Set aside.
In a large frying pan heat the cooking oil until very hot but not yet smoking. Add the pork chops in a single layer and brown quickly on both side until golden. About 2 to 3 minutes per side. You may need to do this in two batches to avoid over crowding the pan if you pan is not large enough.
Place browned pork chops in a 6 quart or larger slow cooker and pour the peach and whiskey mixture over the pork chops.
Cover and cook on LOW for 4 hours.
Serve pork chops with peach sauce spooned over then and enjoy!
