Amaretto Sour

Jeffrey Morgenthaler, the bar manager of Pépé Le Moko and Clyde Common in Portland, Ore., enjoyed amaretto sours as a young man. As a bartender, he embarked on a project to make a better version of this often-mocked drink, which was typically composed of just amaretto and sour mix. He boosted the alcoholic strength by mixing in nearly a full ounce of overproof bourbon, replaced the sour mix with real lemon juice and added an egg white — a common ingredient in many sour recipes from the past. Given all the alterations, he might have given the cocktail a new name, but decided against that. “There wouldn’t have been any point,” he said. “There’s a big difference between if I took this drink and made it good, and if I invented a new drink with amaretto. The latter wouldn’t have the same gravitas.” —Robert Simonson
