Frosted Grapes A blending of chilled fruits with honey, liqueur brandy and sour cream. This dessert must be chilled overnight in order to blend its flavors.  Wash and pick over the grapes, removing all stems. Place in a serving bowl, pour over the honey, brandy and lemon juice. Mix well and place in the refrigerator. Stir occasionally (before you go to bed, and once or twice in the morning while you are having coffee . . .). Stir again while you are preparing the main dinner courses—and finally place in dessert dishes, topped with a half cup of sour cream for each portion. 1 pound seedless grapes 1/3 cup honey 2 T each of good Cognac brandy and lemon juice 1 pint sour cream
