Place the chopped apples into a large saucepan and add about 1” of apple juice. Cook until the apples are soft and tender. If there is excess liquid after cooking the apples you can drain this off and save to drink as ‘juice’, that’s exactly what it is.
Mash the apples with a potato masher or put through a food mill. You could also use a food processor or blender. Add cinnamon to taste and sugar if needed. Keep hot or cool and store in refrigerator for a week.
That’s it!
