Core apples and cut into large chunks. Place into electric pressure cooker with water, lemon juice, and cinnamon. Mix well.
Secure the lid and set to cook on High pressure for 5 minutes. Once done, allow pressure to naturally release for 20 minutes.
Uncover and mash, using a potato masher, to chunky consistency. For smoother applesauce, use an immersion blender.
Optional: mix in maple syrup.
