In a saucepan, combine apples, water, sugar, and cinnamon.
Cover, and cook over medium heat for 15 to 20 minutes, or until apples are soft.
Blend in your blender for about 15 seconds. Serve warm or chill and serve.
Notes
You can easily decrease the amount of sugar and omit the cinnamon if you want a healthier applesauce. If you are going to store for a while it will keep longer with the sugar in it.
