Wash the pears.

Core all the pears and cut into 1 inch cubes.

Put the pears into the crock pot.

Add the dates, lemon, water, and cinnamon to the crock pot.

Turn the crock pot on low and let them cook about 12 hours. (I cook them while at work).

With a stick blender or potato masher puree the cooked pear mixture until as smooth as you like it.

Let cook another 3 hours (keep the lid off if you want it really thick).

Store in a air tight container in the fridge for one week. Freeze some for 3 months.
