1. Peel and core the apples, then cut into small chunks about 1-inch in size.
2. Transfer the apple chunks to a large pot and add water, lemon juice, and the cinnamon stick.
3. Cover and bring to a boil over medium-high heat.
4. Reduce heat to low, keeping the pot covered, and simmer for 20-30 minutes, stirring occasionally, until apples are fork-tender.
5. Remove the cinnamon stick from the pot.
6. Use an immersion blender, food processor, or standard blender to puree the apples to your preferred consistency – smooth or chunky.
7. Taste the applesauce and incorporate any optional ingredients if desired.
8. For a sweeter, dessert-style applesauce, return the puree to the pot after blending and stir in brown sugar, butter, ground cinnamon, and/or vanilla extract. Cook uncovered over low heat for about 10 minutes until slightly thickened.
9. Allow to cool before transferring to storage containers.
