Skim the fat layer off of fully cooled bone broth (optional, but this will extend the shelf life)
Rewarm the bone broth (in a crockpot on high or a stockpot on the stove)
Meanwhile, heat up your pressure canner and fill your canning jars with hot water to warm them up
Working with 1-2 jars at a time, dump out the hot water and filling it with hot bone broth using a ladle. Leave 1" of headspace.
Use a cloth dipped in white vinegar to wipe the jar rims, then secure with a canning lid and ring until fingertip tight.
Place jars into the hot pressure canner as you fill them.
Once the pressure canner is full, secure the lid following the manufacturer's instructions.
Vent steam for 10 minutes, then add the weighted gauge for 10 pounds of pressure. *If you are above 2,000 feet elevation use 15 pounds of pressure
Process for 20 minutes if using pint jars or 25 minutes if using quart jars
Once the time is complete, turn off the heat and let the pressure slowly release naturally to 0.
Carefully remove the lid and transfer the hot jars to a heat-resistant surface (I use a cutting board) and let them fully cool.
Once at room temperature, remove the rings and test the seal. Move sealed jars to your pantry for long-term storage. Move any jars that did not seal to the fridge to be consumed within a few days.
