Preheat oven to 350 degrees F. Peel and core the apples, then slice thinly. Put them into a saucepan with water and raisins (if desired), then cover and cook for 15 minutes, until soft. Cut bread into fingers and arrange half in a pie dish, butter side down. Cover with apple mixture, then top layer with bread, butter side up. Top with sugar and spices. Bake for 20 minutes, until crisp.
