Adapted from a recipe by Fabio Viviani. Reducing the quart of beef stock to 1 1/2 cups is not included in prep time and a must for a good depth of flavor. A good stout beer is also a must for this recipe, I use Guinness extra stout. Boneless or bone on ribs can be used for this recipe. I have stated 8 hours for cooking time but that will depend on your crock pot, with mine the bone on ribs were almost done at the 6 hour mark so I turned the warm cycle on and let simmer for 2 more hours, they were perfect.
