Saute apples, almonds, onion, and celery in butter for 5 minutes, stirring frequently. Remove from heat. Stir in cinnamon, poultry seasoning and salt. Toss together bread cubes and raisins; add apple mixture. Stir egg in one third (or 0.5) c apple cider; toss into bread mixture. Add remaining apple cider if a moister stuffing is desired.
Use to stuff a 15 to 20 lb turkey, or two large roasting chickens. Spoon any remaining stuffing into a lightly greased 9x5 loaf pan. Bake, covered, during the last 30-40 minutes of roasting.
