In a large mixing bowl, combine the lemon juice and sugar. Toss the apples and bananas in the mixture to prevent them from turning brown. Add the remaining fruit. In a small mixing bowl, whisk together the sour cream and grenadine. Add the sour cream mixture to the fruit and stir together, coating the fruit completely. Hold covered in the refrigerator until ready to serve. Just before serving, toss the fruit once more to redistribute the dressing.

Yield: 8-10 servings

* Do not cut the banana or apple until the lemon juice and sugar are combined. Place the fruit into the lemon juice mixture as soon as it is cut.
