Wait for your broth to cool a bit before transferring it to clean glass mason jars, or they can break. Your bone broth will stay good in the refrigerator for about 3 days or freeze it and defrost as needed. It will stay good in the freezer for months (be sure you don’t fill the jars all the way up!).
As a note, I do not skim the fat off of my broth – it adds wonderful flavor!
