Add the pork and sauce and cook over moderate heat, tossing until the sauce is absorbed, 3 minutes. Transfer the noodles to a platter, garnish with scallions and chiles and serve.

Stir in the chicken-pork mixture, 4 cups of the stock and the brewed saffron. Bring to a boil over high heat, then scatter the rice evenly on top, shaking the pan to distribute it evenly.
