Body
Cut and separate ribs into four pieces; pat dry.
Heat oven to 375 degree F.
Mix together dry mustard, salt and pepper. Rub seasoning onto ribs. Heat oil in a heavy bottom pot over high heat, quickly brown all sides of ribs (make sure not to crowd ribs when browning). Transfer meat and to a large plate; set aside.
Heat 3 tablespoon canola oil over medium high heat. Add shallots, carrots, celery, and bay leaves to pot and cook over medium heat, stirring occasionally, until vegetables begin to soften, about 3-5 minutes. Stir in cumin, dry mustard, smoked paprika and tomato paste. Add broth, beer, and tomatoes, then add ribs with any juices and bring to a boil.
Cover pot and transfer to lower third rack. Braise until meat is fork tender, 2 to 2 1/2 hours.
Remove from oven, skim off fat and discard bay leaves. Separate and shred meat away from bones.
To make the gravy
