Preheat oven to 475 degrees.
Generously apply sea salt to the roast.
Heat the cooking fat in the bottom of an oven safe pot on medium high heat. When it is hot, brown the roast on all sides.
Add the bone broth and cider vinegar to the pot along with the fresh herbs if you choose to use them. Ensuring that the lid is on tightly as not to let any steam escape, cook for 3-4 hours, checking periodically to be sure there is enough liquid in the bottom.
Remove the meat from the pot and let cool for a couple of minutes. Meanwhile, strain the juice from the pot and bring to a simmer on the stove to reduce the liquid, about 15 minutes.
Once the meat has cooled a little bit, shred it into bits with two forks.
When pan juice has reduced add back to the shredded beef and combine.
