Peel the apples using a peeler. This removes the skin, which can be tough and bitter.

Core and chop the apples into small pieces (about 1-inch cubes). This helps them cook evenly and quickly.

In a large pot, combine the chopped apples, water, sugar, and lemon juice. The water will create steam to help cook the apples.

Cover the pot and cook over medium heat for about 20 minutes, stirring occasionally. This allows the apples to soften and break down.

After 20 minutes, check the apples. If they are soft enough, proceed to the next step. If not, continue cooking for an additional 5-10 minutes.

Once the apples are soft, remove the pot from heat. Use a wooden spoon to mash the apples directly in the pot for a chunky texture.

For a smoother applesauce, transfer the mixture to a food processor and blend until desired consistency is reached.

Stir in the cinnamon if using, and adjust the sweetness by adding more sugar if desired. Taste the applesauce and adjust flavors as necessary.

Let the applesauce cool to room temperature before serving. It can be stored in the refrigerator for up to a week.

Serve chilled or at room temperature, as a side dish or snack.
