Refreshing Cocktail

Wash the oranges and apples, then slice them thinly, leaving the skin on. Pour over a syrup made from water and sugar. Cover and let it sit for 12 hours. Before serving, add chilled white wine and sparkling water, then pour into glasses. Add a cube of ice to each glass. Before freezing the ice, place a berry of strawberry or cranberry in each ice cube tray. Serve with straws.
