I'm an inexperienced cook, and new to Paleohacks. Recently, I've been making bone broth almost every day. I use chicken feet, vegetable scraps, vinegar, spices, and sometimes other bones or meat. I cook for 6-12 hours, strain the broth, and discard the solids. (The neighborhood cats love me)
I've noticed that the bones (and some of the vegetables) that I'm throwing away are pretty much intact. I don't see any problem with putting the solids in the freezer overnight, and adding them to tomorrow's broth, along with some fresh ingredients.
But what if I do this repeatedly? Before long, I would wind up with bones meat and veggies that have been cooked all day, then frozen, many times, mixed in with relatively fresh ingredients. Is this ok, or should it be avoided?
