If I use a turkey or something I have surplus and freeze in wide mouth jars (no shoulders), but usually, I use it up so fast with the crock pot on warm for several days, I never store.
Sometimes, I put a gigantic jar in the fridge and just add the broth to soups and things for the next 4-5 days.
I skim the tallow off the top after a short stint in the fridge (so much easier, and less broth gets wasted that way), but I generally have one nice cup unskimmed.
With lots of salt.
The guy who butchers grass fed beef gives people free bones...I have a freezer FULL of beef bones from friends who don't know what to do with theirs or don't want them.
