1 cup fresh seedless grapes, halved
1 cup fresh whole blueberries
1 cup fresh strawberries, halved
1 cup fresh peaches, cut in bite sized pieces
1 cup firmly packed brown sugar
2 cups dairy sour cream
In shallow 0 by 12 inch glass dish, combine all fruit and mix well.  Sprinkle brown sugar over the fruit.  Top with sour cream.  Cover with plastic wrap; refrigerate 3 to 4 hours or overnight.  The sour cream will seep through the brown sugar to the fruit.
To serve, gently stir the fruit; spoon into sherbet glasses.
