I roast a whole chicken or turkey. I take most of the meat off the bones, drain off the liquid and stick it in the fridge and throw the carcass in a big pot with water and boil it down. Then I put it through a strainer and pick the rest of the meat of. If it comes with the gizards and neck I boil those down and save the broth.
I'll drain the fat off the liquid from the chicken I usually make the soup the next day so the fat has risen to the top and hardened and is easy to take of. I add that to the broth from the big pot and add the broth from the gizards. You can add bullion or culinary chicken stock but I don't usually need it.
then I cut up carrots and celery, add some salt and pepper to taste and let it boil. From there I add as much meat as looks good and serve. I usually make enough to freeze.
We don't add noodles or rice until ready to serve and I don't freeze it with noodles or rice.
All that being said. I once made a huge pot of turkey soup for a sledding party. Used a 20 lb turkey, we're talking a lot of soup. I get to the park, my leg cramps up and I knock the soup out of the car and on to the ground...
So, I still had turkey because I had extra that I had sliced for sandwiches and we were cooking the noodles there.
So we went to the store, bought bullion, carrots and celery, put it togheter in about and hour and you know what, everybody loved that stupid soup that I didn't labor over
But I still make the real thing for our sledding parties, I'm just not allowed to tranport it any more.
Good Luck
