In a large stockpot or Dutch oven, combine the short ribs and brisket, cover with cold water, and bring to a rapid boil over high heat. With tongs, transfer the meat to a large bowl and discard the water (this is done to create a clear broth). Rinse out the pot, return the meat to the pot, and add the onion, bay leaf, savory, thyme, herbes de Provence, salt, peppercorns, star anise, cinnamon, and garlic. Add cold water to cover everything by 1 inch.
