Beef Broth

I love soups with a beef broth base. My grandmother and a family friend from long ago made the best beef and vegetable soup. I would just drink the broth and leave the beef and vegetables in the pot! Been trying to duplicate a rich, beefy broth with tomatoes for years and can't get that same exact taste.

So far the best result: roast the neck bones and deglaze the pan with red wine, then simmer for hours in salted water with onions, garlic, canned tomatoes, tomato paste, worcestershire sauce, mushrooms, peppercorns. Once I strain the broth and add the browned chuck roast and vegetables for more simmering, I add some bay leaves, fresh thyme, rosemary and a splash of balsamic vinegar. This came close, but still not quite the same.

How do you make beef broth?
