Preparation:

Cut celery into 1-inch pieces. In a small saucepan cook, covered, in a small amount of boiling water for 10 minutes, drain and refrigerate. For marinade, in a small saucepan combine pineapple juice, oil, cinnamon, salt, nutmeg, and allspice; cook over medium heat for 10 minutes; stirring occasionally. Cool. Place pork in a shallow dish; pour marinade over pork. Cover and marinate in the refrigerator for several hours or overnight, stirring occasionally. Drain pork, reserving marinade. On six 12-inch skewers thread pork cubes and celery, allowing space between cubes. Grill over medium coals about 10 minutes; turning frequently. Push cubes together; thread apple on skewers; grill an additional 5 minutes, brushing with marinade. If using bamboo skewers, soak them in water for 30 minutes before threading meat.
