Peel and core apples. Thinly slice and rough chop them. Add them to a medium-to large pot over medium-high heat on the stove. Add water and stir. Once the water starts to simmer, reduce heat to med-low and stir. Add cinnamon, nutmeg and salt and stir. Cook over medium low heat for 2 hours, stirring occasionally. Depending on how you like the consistency of your applesauce, cook another hour for softer sauce.
