Combine apples, water, sugar and cinnamon in a heavy, deep bottom pot.
Cook over medium heat, stirring as necessary to redistribute the heat, for 15 to 20 minutes, or until the apples are soft.
Taste warm applesauce and add additional sugar if desired or additional water to think if desired.
Let cool slightly and mash apples with a fork or a potato masher.
Notes
Apples: Any apple variety works. Sweeter apples (Fuji, Gala, Golden Delicious) yield naturally sweet applesauce, while tart apples (Granny Smith, Jonathan) add tang. A mix of both gives the best flavor.
Sugar: Adjust to taste. Start with less and add more after cooking if needed. Honey or maple syrup can be substituted.
Cinnamon: A cinnamon stick adds subtle spice. For a stronger flavor, stir in ½ teaspoon ground cinnamon after cooking.
Texture: For chunky applesauce, mash with a potato masher. For smooth applesauce, use a blender or immersion blender.
Storage: Store in the refrigerator for up to 7–10 days or freeze for up to 6 months.
