Beef Brisket with Cola

In a bowl, combine the cola, Worcestershire sauce, vinegar, garlic, beef bouillon granules, dry mustard powder, chili powder, and cayenne pepper. Mix well to combine. Set aside 1/2 cup of the mixture for the sauce.

Place the onions in the bottom of the crock pot. Cut the meat to fit the crock pot if necessary and place the meat on top of the onions. Pour the cola mixture over the meat. Cover and cook on low heat for 10 hours or on high heat for 5 hours, or until the meat is tender (cook time may vary by crock pot).

For the sauce, combine the reserved cola mixture, ketchup, and butter in a saucepan. Heat over medium heat until it simmers, stirring occasionally. Remove from the heat and let cool.

Remove the meat from the crock pot and shred with two forks. Return the meat to the crock pot if not serving immediately.

Serve the shredded beef on buns or warmed tortillas with the sauce, as desired.
