Pick over the carcass and reserve any tender morsels of meat. Use this for the cup of meat indicated, adding more meat as necessary.
Place the carcass in a kettle and set the meat aside. Add to the kettle any jellied gravy that may have accumulated on the turkey platter.
Add the water to the kettle. Add the leftover giblet gravy, onion, bay leaf, salt, pepper, cloves, parsley, thyme, carrots, and celery. Bring to the boil and simmer 1 hour, skimming the surface as necessary.
Strain the soup through a sieve lined with a clean kitchen towel or a double thickness of cheesecloth. Discard all the solids except the carrots and celery.
Pour about 2cups of the soup into a saucepan and add the vermicelli. Cook until just tender.
Add this to the soup. Cut the carrots and celery into ½-inch cubes and add them to the soup. Add the cubed turkey meat and bring to the boil. Serve piping hot.
