Back to basics with a standard whiskey sour recipe - whiskey, lemon, simple syrup and a touch of bitters combine to create an easy sipping tipple for a warm afternoon in the sun. Or late night by the pool.
To make the champagne simple syrup, take 1 cup of champagne and add 1 cup of sugar. Heat it just enough for the sugar to dissolve, then take it off the stove, let cool completely and refrigerate.
