1 gallon of water 2 tbs apple cider vinegar 2–4 lb of animal bones salt and pepper, to taste
Place all ingredients in a large pot or slow cooker. Bring to a boil. Reduce to a simmer and cook for 12–24 hours. The longer it cooks, the better it will taste and more nutritious it will be. Allow the broth to cool. Strain it into a large container and discard the solids.
