For the Meat

1. Combine the Spice Mix ingredients in a bowl. Sprinkle half over the beef and rub it into the meat.
2. Heat the olive oil in a large heavy-based pot over medium heat. Add the remaining spices and roast them until they are fragrant then turn the heat to high and add the beef and cook it’s sealed and golden on all sides. Set aside on a plate
3. Turn the stove down to medium. If the pot looks dry, add more olive oil. Add the garlic and onion and cook until soft.
4. Add the lime juice, and scrape the bottom of the pot so the brown bits mix into the liquid. Then return the beef into the pot, add the canned tomatoes, bone broth, and enough some filtered water so the beef is mostly, but not completely submerged.
5. Put the lid on, bring to a simmer then turn the stove down so it is bubbling gently, not rapidly. Cook for 2 hours or more with the lid on, then 30 minutes with the lid off so that the sauce can reduce or until the beef is tender enough to shred.
6. While the meat is cooking prepare your salsa and toppings.
7. Shred the beef in the with 2 forks. Mix well, and taste, season if necessary.
8. Now Assemble the tacos as you like.
