In a large mixing bowl, coat the cubed apples with freshly squeezed lemon juice to prevent browning and preserve their crisp texture.
In a separate bowl, thoroughly whisk together the mayonnaise and brown sugar until well combined.
Add the prepared apples, celery slices, halved grapes, chopped pecans, and dried cranberries to the mayonnaise mixture.
Gently fold the ingredients together until evenly coated and well distributed throughout the salad.
Cover the bowl and refrigerate for a minimum of 30 minutes before serving to enhance the flavors and ensure a chilled presentation.
