The thicker skinned, late Summer and Fall apples produce a grainier texture that's best for applesauce.
Stir applesauce, sugars, and cider together and cook in a slow oven (325℉ (160℃)) for 3 hours, stirring occasionally.
Return to oven and cook 1 hour more.
Apple butter requires long, slow cooking.
(Can also be made in a crockpot)
