Use a 6-quart slow cooker. Put the pork into the bottom of your cooker. In a mixing bowl, combine all of the dried spices. Rub this mixture evenly over all sides of the meat.
Add the carrot,sauerkraut, and caraway seeds. Cover and cook on low for 8-10 hours. Shred the meat completely using two large forks, and serve on toasted gluten-free buns, with yellow mustard, if desired.
