2 to 5 pounds pastured pork bones (neck, joint, and/or shoulder bones)
3 tablespoons apple cider vinegar
filtered water to cover the bones
Place thawed bones into the stainless steel insert of your Instant Pot.
Add enough water to cover the bones, but no more.
Add apple cider vinegar.
Place the lid on the Instant Pot, checking that the seal is in place. Press the "Manual" or "Pressure Cook" button and adjust the time to 120 minutes on high pressure. Seal the vent.
When it beeps, you can immediately release pressure or allow it to naturally release, depending on your needs.
Strain the bones from the broth. Refrigerate, freeze, or can and enjoy!
