Peel, core and large dice your apples. I found if you mix varieties you'll get great results but it really doesn't matter

Bring to a good simmer, and simmer until the apples are soft, about 20 minutes

At the end, sprinkle cinnamon and stir. My batch of 8 apples used 1 tablespoon of cinnamon

Let cool until lukewarm, scoop into either a food processor or blender (liquid too!) and pulse until smooth

That's it! Enjoy! Keep covered in the fridge for up to a week
