Casino
A Casino is 40ml of Old Tom gin, 10ml of maraschino liqueur, 10ml of fresh lemon juice and two dashes of orange bitters, shaken hard for 10 to 12 seconds and double strained into a chilled coupe, with a lemon twist and a maraschino cherry. About 2.0 UK units. The measures are the IBA’s. There is no syrup. Old Tom is a lightly sweetened gin, and that sweetness, with the maraschino’s, is all the sugar the lemon has to meet. With a London Dry the drink turns sharp. Difford’s Guide traces the Casino to Jacob A. Didier’s 1909 book The Reminder, and says Hugo Ensslin printed an almost identical recipe in 1916, in the same book that gave the first published Aviation. The two drinks share gin, maraschino and lemon; the Aviation adds crème de violette and moves to dry gin.
Glassware: Coupe Glass
Garnish: Lemon twist and Maraschino cherry
Ingredients
40ml
Lightly sweetened gin at about 40% ABV. Its sweetness balances the lemon; a London Dry makes a sharper drink that needs a little syrup.
10ml
Luxardo, the IBA’s named bottle, at about 32% ABV. Clear, with a cherry-stone almond edge, and sweeter than it tastes; not the syrup from a jar of cherries.
10ml
Squeezed the same day. A short measure for a sour, set against two sources of sugar.
2 dashes
Two dashes. They bring peel and a little bitterness that links the lemon to the maraschino.
Instructions
Chill a coupe.
Squeeze the lemon juice the same day.
Add the Old Tom gin, maraschino liqueur, lemon juice and orange bitters to a shaker.
Fill with cubed ice and shake hard for 10 to 12 seconds.
Double strain into the chilled coupe.
Express a lemon twist over the drink, drop it in and add a maraschino cherry.

Expert Tip
Use Old Tom, and taste it first. Its sweetness is the only sugar besides the maraschino, and bottles vary. If yours is on the dry side, a barspoon of sugar syrup brings the drink back. Measure the maraschino. At 10ml it reads as cherry and almond under the gin; at 20ml it takes over and the almond turns medicinal. Squeeze the lemon the same day. There is only 10ml of it, so a tired juice leaves the drink flat and sweet.
Behind the Casino
Flavour Profile
Didier, 1909, and Ensslin, 1916
Difford’s Guide traces the Casino to Jacob A. Didier’s 1909 book The Reminder. His measures are loose: one drink of Tom gin, two dashes each of lemon juice, maraschino and orange bitters. Difford’s says Hugo Ensslin, head bartender at the Hotel Wallick in New York, printed an almost identical recipe in his 1916 Recipes for Mixed Drinks, so it would appear that he copied Didier.
Ensslin’s book also holds the first published Aviation, as the Oxford Companion has it, and Difford’s calls his Casino essentially a stirred Aviation without crème de violette, with a lot more lemon juice.
Old Tom Carries the Sugar
Old Tom sits between genever and London Dry: similar botanicals to a dry gin, lightly sweetened. In the Casino that sweetness, with the maraschino’s, is all there is to balance 10ml of lemon. No syrup is added.
Swap in London Dry and the balance tips sour, with the maraschino’s almond note left on its own. A barspoon of sugar syrup fixes it, though the drink is then close to an Aviation without the violette.
Ten Millilitres of Maraschino
Maraschino is made from marasca cherries, stones included, and the stones give it a bitter almond edge. At 10ml it scents the drink more than it flavours it: you smell cherry and taste gin and lemon. Luxardo is the bottle the IBA names.

How to Serve It
Up, very cold, before dinner. It is short, so make it just before it is drunk; served up it has nothing to keep it cold. The IBA’s rocks glass suits a slower drink.
For dry gin and violette, make an Aviation; for Old Tom with sweet vermouth and maraschino, a Martinez.
Make it at home
The Spirit
Old Tom GinOld Tom is gin with a little sugar added, counted at 40% ABV in our recipes, and rounder and softer than London Dry. The retained Regulation (EC) 110/2008 gives the name no definition: it is sold as gin, and because it is sweetened it cannot be labelled dry. Four of our recipes ask for it, the Tuxedo, the Turf Club, the Casino and the Ford Cocktail, where its sugar balances vermouth or lemon.

Aviation
An Aviation is gin, maraschino, lemon and a little crème de violette: 45ml gin, 15ml maraschino liqueur, 15ml fresh lemon juice and one bar spoon of crème de violette, shaken hard and double strained into a chilled coupe, with a cherry dropped in. The measures are the International Bartenders Association’s. The violette gives the drink its pale blue-violet colour. Hugo Ensslin, bar manager at the Wallick Hotel in New York, published the original formula for the classic Aviation in his 1916 Recipes for Mixed Drinks, the Oxford Companion says. In 1930 the Savoy Cocktail Book printed it without the violette, and many bartenders followed that version. Keep the violette to a bar spoon: more turns the drink soapy and purple. A glass holds about 2.4 UK units.

Last Word
A Last Word is 22.5ml each of gin, green Chartreuse, maraschino liqueur and fresh lime juice, shaken hard for 10 to 12 seconds and double strained into a chilled Nick & Nora or coupe. About 2.9 UK units. The measures are the IBA’s; the cherry or lime twist is ours. The Oxford Companion says the drink first appears in print in the Detroit Athletic Club News in 1916, on a menu at 35 cents, a high price then. Ted Saucier’s Bottoms Up of 1951 prints the recipe, quoting a club source who says Frank Fogarty, a vaudeville monologist, introduced it there about thirty years earlier. In 2003 Murray Stenson put it on the menu at the Zig Zag Café in Seattle, from where it spread, the Companion says. Four strong flavours at equal volume, and none takes over. Chartreuse brings herbs and heat, maraschino cherry and a bitter almond edge, lime the acid, and gin holds them together.
Gin Sour
A Gin Sour is 60ml of London Dry gin, 25ml of fresh lemon juice and 20ml of sugar syrup, shaken hard with ice for 10 to 12 seconds and strained over fresh ice in a rocks glass, with a lemon wheel and a cherry. About 2.4 UK units. Add 15ml of egg white for a silkier version, dry shaken first; it is raw, so leave it out for anyone allergic to egg. It is the plain sour with gin as the spirit. Difford’s Guide says Jerry Thomas’s 1862 bar guide has a Gin Sour, and the frame of spirit, citrus and sugar runs under most gin classics since: the White Lady sweetens it with orange liqueur, the Bee’s Knees with honey, the Clover Club with raspberry. With only three ingredients the gin has nowhere to hide. A juniper-led London Dry gives the classic reading; a citrus or floral gin changes the drink more than any change of measure.
