Chicken giblets and stock

[JimmyMcNulty]

I've got the remains of a roast chicken, and a bag of raw giblets that I now realise (having searched on here) I should've used to make gravy. Is it a big no-no to make stock from the cooked bones AND the raw giblets all together?

That would work.

Fry the giblets with some chopped onion, celery and carrots in a little butter, then add it all along with the carcass into a big pot, plenty of water and simmer for a couple of hours.
