In a large stock pot, pour cold water over the bones, add vinegar sea vegetables and vegetable trimmings and gently bring to a boil. Gently simmer all ingredients. A scum will form once bones begin to simmer, skim this off and discard. Cover and replenish water as necessary. Boiling time should be between 24-48 hrs, the longer the better! I simmer mine overnight to extract the most possible minerals and nutrients from the bones.
