In a 12 quart (or larger) stock pot, over high heat, add water, apples and lemon juice. Stir to combine and cover. Once boiling rapidly, reduce to medium high and cook until apples are soft, stirring often so apples do not stick to the bottom. Approximately 20 minutes.

Working in batches, transfer apples to blender or food processor and blend until smooth. Return to pot and bring back to a boil. Remove from heat and process for canning or refrigerate.

Process canning jars according to manufacturers directions or keep in refrigerator.
