J.P.
I do this and mash it up for applesauce or keep them whole for a dessert. Just slice apples, add water to cover bottom of pan, add sugar and cinnamon (you can always add more later after tasting it) and let it boil/simmer on the stove for about 15 min. depending on the number of apples. When they're as soft as you want them, either mash or put them in a dish!
