Place the rinsed and salted oxtails into cold salted water and bring to a boil. Reduce heat and simmer, occasionally skimming the foam from the surface.
When meat is tender, remove the oxtails and add celery, onions, carrots and cloves.
Cook until the vegetables are tender. Salt and pepper to taste.
Remove meat from the tail and place in tureen, pour soup over it and serve very hot.
