1Begin by preparing the broth: Place beef short ribs and chicken drumsticks in a large pot. Cover with 3000 grams of cold Water. Bring the Water to a boil, then carefully skim off any foam that rises to the surface.
2Add the Carrots, Celery stalks, Yellow onion, Black peppercorns, and Salt to the pot. Reduce the heat to a gentle simmer, cover partially, and cook for at least 3 hours, or until the broth is rich and flavorful.
3Once the broth is cooked, strain it through a fine-mesh sieve, discarding the solids. Keep the finished broth warm over low heat while you prepare the tortellini.
