Peel, core and slice or chop apples - they will get pureed so it doesn't need to be pretty, just keep your pieces relatively similar sizes.
Add all ingredients to a large enough pot and turn burner to medium heat and cover. Stir every 5-10 minutes to make sure apple chunks all get even cooking time toward the bottom of the pan in liquid. Cook about 30 minutes until apple pieces are soft.
Use an immersion blender to puree everything together - if you are worried about scratching the pot used, transfer ingredients to a bowl before blending. You can also use a regular blender if you have one large enough!
