Remove corned beef from packaging and rinse with cold water. Place beef in a container and soak in cold water for 3 hours, draining and refilling the water every hour to remove excess salt from meat.
Pre-heat smoker to 250°F using hickory wood.
Combine the dry ingredients (minus the beef broth and mustard) in a bowl and mix thoroughly.
Rub pork tenderloin with mustard and sprinkle the seasoning evenly on all sides of the corned beef.
Place the beef directly on the smoker rack away from direct heat. Spritz with the beef broth every 45 minutes to keep moist.
Smoke until an internal temperature of 150°F, about 3-4 hours.
Remove beef from smoker and wrap tightly with aluminum foil. Return to the smoker and smoke until and internal temperature of 195° to 203°F. A 203° IT will produce a more tender smoked corned beef than finishing at 195°F.
Allow to rest for 10 minutes before slicing into ¼" pieces AGAINST THE GRAIN. This should be slicing across the beef creating short oval pieces.
Serve and Enjoy!!! Don't forget to comment and rate this recipe. Thanks!
Notes
Want even more tender? Instead of wrapping in foil, place meat in an aluminum foil pan and add ½-1 cup of beef broth. Cover and smoke until 203° internal temperature.
Serve with brown mustard, dijon mustard, or yellow mustard on the side.
