Is it ok to use the cooked bones from, say, a rib roast to make bone broth? Or is it better to start with uncooked bones?
Using basic chemistry knowledge, I would have to think that using cooked bones might probably yield a lower mineral concentration as opposed to fresh-uncooked ones (weight for weight of the same with same cooking technique).
But I don't think it's bad in any way, only that you might want to consider it (if right) to make sure you get enough minerals. Maybe you will need a bit more cooked bones to get same quantity of minerals as opposed to fresh ones. That's pretty much all.
Anyhow thanks for the thread! I have tried to find a similar one but now it has been done.
Peace.
