I started posting my Bone Broth recipe every now & then on the birdsite about 15 yrs ago. It’s my own recipe I came up with about 25 yrs ago. It may be a coincidence, but a couple of years after I started posting the recipe, bone broth became a big thing.
The bones from 1 baked chicken
A lot of water
Salt
Boil the chicken bones in water with a little salt for 3+ hrs
Strain out bones with a fine wire mesh strainer into a bowl
Divide into 3, freezing 2/3 s in 2 ziplocks, use other 1/3 for soup
