I don't have one way to make applesauce, it really varies. Most often I use a variety of apples, a little salt and a glug of Calvados. Sometimes I leave the peels on and put it through the food mill, sometimes I peel in advance so that I can have chunks of apple still in my sauce. Other potential additions, aside from Calvados, are orange zest or juice, lemon juice, nutmeg, cardamon, cinnamon, a little sugar, Grand Marnier, or cider. I don't add much sugar and generally find the simpler the better.
