A leftover turkey carcass is used to make a delicious broth, which is then used to make a warming soup akin to the italian favorite tortellini en brodo. The recipe is written for 1 pound of carcass--for each additional pound, double the aromatic ingredients (carrot, onion, celery, parsley and peppercorns; do not add more bay leaves) used to enhance the broth's flavor. For more tortellini, you will need about 8 cups turkey broth for every 9 ounces of tortellini.
