All week long, Jeffrey Morgenthaler of Portland's Clyde Common and Pepe Le Moko will be sharing recipes and techniques from his new book, The Bar Book: Elements of Cocktail Technique. Follow along to win one of five copies we’re giving away -- and to perfect your at-home cocktails.

Today: A trick for the frothiest cocktails, and a recipe to shake up tonight.  

Jeff Morgenthaler  White Lady 

Bartenders learned long ago that they could create a creamy mouthfeel in a cocktail, without the flavor and fattiness of cream, simply by adding a dollop of whipped egg white. Drinks containing egg whites benefit from an initial shake without ice -- called a dry shake -- which will develop a thicker, more voluptuous and stable foam. Chad Solomon, former bartender at New York’s Pegu Club and partner at the beverage consulting company Cuffs & Buttons, has championed the technique, though bar historians have recently found references to the method that go back decades.

In their natural state, the proteins in egg whites are curled up tightly in little balls. As you whisk or otherwise agitate the whites, those protein balls are slammed around, and the impact loosens the bonds. The balled-up proteins begin to unfurl and form new bonds with other proteins, rather than with themselves, which creates a loose network. If you continue to agitate, you begin to introduce air bubbles into the network. The air is captured by the proteins, and the result is foamy or fluffy whites, depending on how far you go. Proteins will stretch and unwind more easily if they’re given some time to loosen up rather than being rushed into the process. A chef usually whips egg whites more slowly at first and then turns up the speed once a light foam has formed. The dry shake accomplishes this for the bartender.

The dry shake also just allows more total time for you to shake the whites -- once you add ice, you’re limited as to how much shaking you can do because you can’t risk over-diluting the drink with melting ice. So shake first to get a good foam established, and then continue with ice, which will create even more agitation and foam.

More: If you don't feel like separating your eggs, use a whole egg -- and make a Negroni Flip.

Another way to jump-start a good foam is to pre-froth the whites using a small electric whipper, such as the Aerolatte. It's intended for whipping milk for espresso drinks, but perfect as an adjunct bar tool. Some bartenders will remove the spring from a spare Hawthorne strainer and toss it in the shaker with the drink for even greater whipping power, though I use Mr. Solomon’s dry shake with fantastic results. I also don’t have to deal with a steel spring covered in sticky egg-white cocktail when I’m done, so I’ve got that going for me.

Shaking Egg Whites  How to Shake a Cocktail

The original White Lady recipe in Harry Craddock’s Savoy Cocktail Book, published in 1930, doesn’t contain any egg whites. However, almost every recipe you’ll find after that inexplicably does. Maybe it’s because bartenders learned what I learned: While a White Lady made without egg white (a gin sidecar, essentially) is a great drink, one made with egg white is absolutely sublime. I’ve taken a few other liberties with this drink, but my favorite has to be the addition of the thyme-infused Cointreau.
