I've always made my own chicken, turkey and beef broth, but I just freeze it flat, in plastic bags. It works ok, but I always forget to take it out ahead of time and then need to thaw it when I'm cooking. I came across a post at Simply Canning about canning your own broth and I thought, "Cool!".
I followed her directions, boiled up the turkey carcass with some additional seasoning, celery, carrots, onion and garlic and figured out my pressure canner and, "Voila!"
9 pints of turkey broth. I am thrilled at how easy it was and now I can free up some freezer space.
