Place them in a food processor in batches of three.
Pulse until the fruit is finely grated.
Transfer the fruit to a crock pot.
Add in the brown sugar, honey, salt, and nutmeg.
Stir the ingredients together.
Add in the cinnamon stick and set on high for 4 hours.
Remove the cinnamon stick and transfer the fruit mixture back into a food processor and mix until smooth. I used a blender wand and used it directly into the crock pot. Or you can blend in small batches in a blender.
Add the cinnamon stick back in.
Transfer the mixture back into the crock pot and set on low for 4 hours until the butter is thick and brown.
You can do the last four hours on high, but make sure to watch the mixture so it doesn't burn.
Once cooled place the pear and apple butter to airtight containers and refrigerate.
