First of all, cut and boil the chicken. If desired, you can boil the whole bird and cut it up after. In the water where the chicken will be cooked, add black and allspice, bay leaf and onion.
Cook the broth over low heat, removing the resulting foam, until the bird is ready. Add salt to the broth to taste, remove the meat, strain and add saffron. Cover with a lid and give it time to brew.
