For his Pisco Sour, Deke Dunne adds soda water to the second stage of a reverse dry shake to create fluffy egg white peaks that have real staying power. To compensate for the dilution from the soda water, he cuts down on the length of his shaking in both stages, which results in a smooth head and luscious texture.
