In a medium pot, place apples, water, lemon juice, salt and sugar and bring to a boil. Reduce heat to medium-low and cover. Allow apples to cook, stirring occasionally until they’re tender and start to break down, about 15-30 minutes depending on how chunky you prefer them. Remove pot from heat. For a slightly chunky applesauce, mash the apples using a potato masher, fork, or pastry cutter. For a smooth applesauce, blend using an immersion blender or food processor.
