Cut away rind and most fat from pork; remove all meat from bones, cut into pieces about 1- half inch thick and 8 cm to 10 cm long. Put pork pieces and chicken in a large bowl, cover and refrigerate until needed. To prepare seasoning, heat the allspice berries over medium heat in small saucepan 3 to 4 min, stirring often; 2 tbs at a time, crush berries in mortar and pestle. In medium bowl, combine berries, nutmeg, cinnamon, scallions, garlic, pepper and 1 tbs vinegar; crush into pasty mixture. Add rest of vinegar, oil, salt, pepper and bay leaves. Turn mixture over pork and chicken and rub meat with seasoning, coating evenly. Cover and refrigerate 2 hours or overnight. Cook jerked pork and chicken on grill over hot coals or on gas barbecue as far from heat as possible (6 inch or more); cover with lid; turn meat every 10 minutes for about 1 hour, until done. If desired, halfway through cooking time toss 1 tsp whole allspice berries into fire. Cut cooked pork into 1 cm slices and serve with chicken. Accompany with Pickapeppa sauce. Serves 6 to 8. (Note: Can also be cooked in preheated 180ºC oven on rack in roasting pan about 1 hour, turning once, but you won't have the grill flavor. (Pickapeppa sauce is a bottled Jamaican condiment available in better supermarkets and gourmet stores.) ----
