Anyone who spends half their time on an airplane searching for the newest designs always looks forward to the comforts of home. In this case it is a sparkling version of a “whiskey sour”.
(if you need to sweeten it add a teaspoon of agave)
Vigorously shake the whiskey, lemon juice and egg white in a shaker. Once there is a bit of froth pour over ice in a double old-fashioned glass. Top generously with Polar® Seltzer.
