Thread the ham cubes on small, wet bamboo skewers, alternating them with the papaya cubes and leaving enough room at one end of each skewer to handle. Combine the remaining ingredients in a small bowl. Dip the skewers in the seasoned butter and broil, preferably over charcoal, 3 to 4 inches from the heat, turning and basting occasionally with the butter, about 6 minutes or until the ham and papaya are glazed and lightly browned. Arrange the skewers on a heated platter and serve hot. Makes 8 servings.
