Salt and pepper the bones (this is in addition to the ingredients above) and bake them in the oven at 400 degrees for 25-30 minutes or until golden brown. If making in the Instant Pot, you can also use the "Saute" option to broth the bones. I have also thrown the bones in completely frozen and it works too but provides a bit different flavor.
Add all ingredients to stock pot or Instant Pot.
If cooking on the stove top, bring to boil and reduce heat to simmer for 8-24 hours. Skim fat and impurities off the top occasionally especially after the first hour.
If cooking in the Instant Pot set the "Soup/Broth" option for 3 hours. Also, set the "Keep Warm" option, so it depressurizes more slowly to lock in more nutrients.
