Looks like a milkshake and goes down like one too. Egg whites are the beginning to this drink, causing some to raise an eyebrow and others to raise a glass to this wonderful age-old cocktail. The original Gin Fizz cocktail used soda, but replace that with champagne and you’ve got a silky fizz.
The Larchmont on Melrose and Lucerne is the best place to try one for yourself.
