In a large mixing bowl, combine ¾ cup mayonnaise, 2 tablespoons fresh lemon juice, 1 tablespoon sugar, and a pinch of kosher salt. Whisk these ingredients together for about 1-2 minutes until the mixture is smooth and creamy.

Core and dice 2 cups of your favorite apples, preferably Granny Smith. Next, dice 1 cup of celery, ensuring the pieces are small. Halve 1 cup of seedless grapes. Toast and chop 1 cup of walnuts or pecans.

Add the diced apples, celery, halved grapes, and toasted nuts into the bowl with the dressing. Gently toss the ingredients together for about 1-2 minutes.

Taste the salad and season with additional kosher salt and freshly cracked pepper as desired.

Transfer the finished Waldorf Salad into an airtight container and chill it in the refrigerator for at least 20-30 minutes.

Serve the chilled Best Waldorf Salad on a bed of butter lettuce or arugula.
