Soak raisins in hot water to cover to soften for about 5 minutes, drain and dry on a paper towel. Combine apples, raisins, and celery in a bowl.
In a separate bowl combine salad dressing, lemon juice, and sugar. Pour the dressing over the fruit mixture and stir.
Refrigerate for about an hour to chill then serve.
If you use Miracle Whip, know that it is sweeter than mayonnaise and will result in a sweeter dressing.If you chop the apples ahead of time, toss them with a little water and a teaspoon of lemon juice to keep them from browning.
