EDF Apple-Pear Butter in the Crockpot

This is something I've been wanting to make since last year, but finally now have the motivation to do it. Most people have probably heard of "apple butter", but really there's a whole slew of fruits you can make "butters" out of. It's not really like actual butter, it's more like a really thick applesauce consistency. And very sweet!
As I'm going through the jars of jam I made, I am planning on making batches of this over the winter. First up? Apple-pear butter. This is from Martha's Everyday Food from Dec 2010. The recipe is on her website.

2.5 pounds each apples and pears. Each peeled, cored, and cut up. You bet I used my food processor for this!

Fast forward 20 minutes to this.....apples on the bottom, pears on the top, some dark brown sugar, and a cinnamon stick.

Stir it all up and cook in the crock pot for 4 hours.

After 4 hours, it looks like this: YUM already.
Take out the cinnamon stick and blend it up in food processor and return it to crock pot. Now it looks a little more like applesauce.

It will darken and brown in color as it cooks, uncovered this time, for 4 more hours. Having this on your counter top uncovered all day and not sampling it frequently is pretty much impossible.

This batch filled up 3 pint jars (16oz ball jars). I have one in the fridge and 2 in the freezer. I believe it keeps for a couple months in the freezer. You can use it on sandwiches or toast or ice cream or whatever! It's basically like really sweet and thick applesauce. It's really great on an English muffin with some actual butter.
