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 deg F.) for 3 hours, stirring occasionally. Add spices. Return to oven and cook 1 hour more. Apple butter requires long, slow cooking. (Can also be made in a crockpot.)
