A riff on chicken Dijon, a classic pan-cooked dish involving mustard and heavy cream. You'll need 18 (8-in.) skewers; if they're wooden, soak in water for at least 1 hour before grilling so they don't splinter or burn.
Simmer bratwurst in the slow cooker along with sauerkraut, apple, mustard and brown sugar to add rich, deep flavor to the sausages. Serve on buns for a hearty main dish.
