Place a large pot over medium heat.  Add ground beef and stir breaking up the pieces a bit.  Add vinegar, Worcestershire, tomatoes, tomato paste, chocolate, baharat and broth.  

Stir mixture, cover and bring to a boil.  Simmer and let cook stirring occasionally for 3-4 hours.  It will thicken up and become a rich and delicious meat sauce.  Add water if needed. 

After cooking let it rest for 30 minutes before serving hot over spaghetti or hot dogs topped with diced white onions.
