Peel, core, and chop the apples into small pieces.
In a large saucepan, combine the chopped apples and water.
Bring the mixture to a simmer over medium heat.
Cover the saucepan and cook the apples for about 20 minutes, stirring occasionally.
Once the apples are soft, remove from heat and let cool slightly.
Use a potato masher or blender to puree the apples to your desired consistency.
Stir in sugar, cinnamon, and lemon juice to taste.
Allow the applesauce to cool completely before serving.
Taste and adjust sweetness if necessary.
Store in an airtight container in the refrigerator.
