Title: Barbeue Beef Brisket
Combine thyme, paprika, pepper, salt, onion powder, garlic powder, cayenne, and cumin in a small bowl; set aside. Rub brisket all over with liquid smoke, then rub with spice mixture.
Pour Worcestershire and barbeque sauce into a slow cooker; place beef on top. Cover, and cook on LOW 8 to 10 hours, until fork tender.
