So here is what you do:
- Dump all bones/carcass & any turkey leftover drippings into a large pot.
- If you want to remove the fat then add some water and put it in the fridge overnight. The fat will rise and congeal a bit and you'll more easily be able to remove it and throw it away.
- I also throw in the neck and giblets if I haven't cooked them up for stuffing, etc.
