Place apples in crockpot and add one cup water, juice or cider.

Cook in crockpot untouched for 10-12 hours.

Using an immersion blender, puree the apples until completely smooth (or to preference)

Add brown sugar and cinnamon.

Replace lid, but leave slightly skewed about one inch so steam will escape (Use chopsticks)

Let cook down for 8-10 hours stirring occasionally

Fill pint jars, wipe rims, and water bath for 5 minutes.
