In a 6 quart Dutch Oven, place apples, water and lemon juice and bring to a boil. Cover and reduce the heat, allowing the apples to cook down for 20-30 minutes. Stir occasionally. Using an immersion blender, blend the apples to the right consistency for applesauce that you prefer. You can also use a food mill or food processor here. After blending, add in the sugar, starting at the low end to ensure that you get the sweetness to your desired level. Then, add in the apple pie spice, starting with 1 ½ teaspoons and adjusting as needed.
