Gin, Dubonnet, and curaçao: Jacques Straub's original Opera Cocktail.
Rum, honey, fresh juices, spices, and the secret ingredient, butter: Don the Beachcomber's Pearl Diver's Punch.
The Royal Bermuda Yacht Club Cocktail: Barbados rum, fresh lime juice, falernum and curacao. A bit of the Caribbean in the North Atlantic.
Gin, vermouth, Benedictine, bitters and absinthe: a Martini with something in it, the Merry Widow Cocktail.
Three Dots and a Dash: rum, juices, falernum, honey, and allspice liqueur. And a most excellent, hallmark garnish.
The Diamondback Cocktail: rye whiskey, apple brandy, and yellow Chartreuse. Simple and herbal, a post-Prohibition version of the Old-Fashioned.
The Conference Cocktail: rye, bourbon, cognac and Calvados. Add some Demerara syrup and Angostura and Xocolatl bitters, and you have a rich mouthful built on the classic Old-Fashioned model.
Brandy, curacao, lemon, and bitters: the Brandy Crusta is the prototype of the modern sour, and a forerunner of the Sidecar. More historic marker than living cocktail, it's a drink that's important to know if you take your cocktails seriously. And it tastes good. Why did it disappear?
Rum, lime juice, honey and champagne: the Airmail cocktail. Make this Prohibition-era Cuban classic now.
The Bloody Mary — salt, pepper, Tabasco, Worcestershire, lemon and, of course, tomato juice. Add vodka for the Bloody Mary, or gin for the Red Snapper.
The Lucien Gaudin Cocktail—gin, Campari, dry vermouth and Cointreau. A fine, orangey riff on the original Negroni.
The Japanese Cocktail, with brandy, orgeat and bitters. The forerunner of the modern, "fancy" cocktail.
