1. Combine the apples, sugar, 1 cup water and 1/2 teaspoon salt in a large pot. Bring to a simmer over medium-high heat, stirring occasionally. Reduce the heat to medium-low. Cover with a tight-fitting lid and cook until the apples are very soft, 18 to 20 minutes.

2. Stir in the lemon juice and cinnamon. Let cool for 5 minutes or so, then transfer the apple mixture to a blender, filling no more than halfway. Remove the center cap from the lid and place it on the blender. Cover the lid with a folded kitchen towel to catch splatters and pulse until smooth. Alternatively, puree in the pan with an immersion blender.

3. Transfer the applesauce to a bowl and refrigerate until cool, about 1 hour. Store leftover applesauce in an airtight container in the refrigerator for up to 5 days.
