The secret to this drink is to shake, shake and shake some more.
Add all the ingredients except the club soda to a shaker and shake vigorously without ice.
Open the shaker, fill with ice and shake again.
Strain into a Collins glass.
Pour a little bit of club soda back and forth between the empty halves of the shaker to pick up any residual egg white, and then pour into the glass.
(This will make for a frothier head.).
