In a large saucepan, place apples, apple cider or apple juice and cinnamon stick.
Cover and simmer, stirring often, over medium-low heat until soft, but not mushy, about 20 minutes.
Remove from heat and let cool.
Using a food mill, placing it over a large bowl, pour apple mixture (remove cinnamon stick) into the food mill and process.
Serves 4 to 6
Note: Use a combination of sweet-tart apples like Gala, Fuji, Jonagold, McIntosh, Golden Delicious for a great tasting sauce.
