We have an apple orchard I go to called Deals over here in Iowa. When I make my applesauce I do add sugar and cinnamon only because it was the 1st time I'd ever made it. I like mine chunky so I can use it in apple crisps too. Sometimes I'll throw a jar into a cake recipe and I feel chunky gives you more choices to use it in recipes other than just eating it.
I did find out one thing when canning applesauce, don't use a pressure canner but use the open water bath...............ask me how I know...:-(
