Makes enough to last for weeks. But heh, what else do you do with that leftover turkey carcass in the fridge? You can just pitch it, but soup is so easy.
Put all the bones, and the rest of the turkey into a big pot filled with water. Bring to a boil, and let it cook for four hours. Put in a bit of onion and chopped celery for flavor. Bell's Poultry seasoning, maybe a tad of pepper, couple of bay leaves. No salt.
After four hours the meat is cooked off the bones. Let things cool a bit. Fish out the bones and pitch them. Cooked bones like these are bad for pets, they splinter into jagged pieces and do bad things to pet's insides when swallowed.
Finish the soup off with some veggies, carrots are good for color, peas, celery, baby corn, or real kernel corn or mushrooms. And some rice. Let it cook at close to a boil until the veggies are tender and the rice is soft. Taste. Salt sparingly if needed. Add salt last, in case it becomes saltier than expected from adding things like bouillon cubes. Serve. Or let it cool and you can reheat it the next day and it will be good.
All the grownups liked it and even had seconds. And I still have plenty left.
