Peel, core, and chop apples into about 1 inch chunks, about 9 cups of raw apples.
In a heavy, nonreactive Dutch oven, combine the apple chunks, water, maple syrup, and cinnamon.
Over medium heat, cover and simmer the apples, stirring occasionally, for about 15 minutes or until apples have softened.
Remove the lid to allow the liquid to evaporate by simmering for the remaining five minutes.
Use potato masher or spoon to break up the apples to desired consistency. Remove from heat.
If necessary, add additional maple syrup or cinnamon to taste.
Serve warm or chilled. Let it cool to room temperature before storing it in the fridge.
