I make my own chicken stock regularly out of either bones from a roast chicken or chicken wings I have roasted. I add onions, carrots and celery cover with water and cook in a pressure cooker for 4 hours to make really rich stock.
This year I would like a good stock for the Christmas gravy, the turkey I have ordered has giblets, but not the gizzard. I don't really know what to do with them.
Would I do the same thing as with chicken bones? Would I roast them first? Are there any bits I should take out or cook differently? Thanks
