A Reader's Heirloom Cocktail: The Mystery of the Pink Bronx

One of the best things about writing a gin site is the post. A reader recently sent us a small treasure: a gin cocktail copied from his grandfather’s personal bartending book, a black notebook titled “White Knights Formulas.” We could not resist tracing where it came from - and the answer leads straight to one of the great, half-forgotten gin cocktails of the early twentieth century.

Here is the recipe exactly as it appeared on page 41 of the book:

Mixing glass 1/2 full cracked ice 2 dashes raspberry syrup 2 dashes orange juice 1/2 jigger French vermouth 1/2 jigger gin Stir, strain into cocktail glass

Is it a real cocktail?

Yes - and a historically grounded one. Everything about this recipe places it firmly in the early 1900s: the handwritten formula book, the period term “French vermouth” (meaning dry vermouth), the measurements in “jiggers” and “dashes,” and the stir-and-strain-up method. The “None genuine without my signature” line is pure old-school bartender pride, from an era when bartenders guarded their personal formulas like trade secrets. This is the real thing: a working bartender’s notebook recipe, most likely from somewhere between the 1900s and the 1930s.

And the drink itself is not an invention. Strip it back to its bones - gin, dry vermouth, and orange juice, stirred and served up - and you have the Bronx, one of the most famous and popular gin cocktails of the pre-Prohibition era.

The Bronx: a great lost gin cocktail

It is hard to overstate how popular the Bronx once was. Created in the early 1900s and widely credited to a bartender named Johnnie Solon at the Waldorf-Astoria in New York, the Bronx was, for a time, mentioned in the same breath as the Martini and the Manhattan - one of the defining cocktails of its age. It is essentially a Martini with orange juice: gin and vermouth (classically both sweet and dry) brightened with a little fresh orange.

Then it faded. As tastes changed and fresh juice fell out of fashion in cocktail bars, the Bronx slipped quietly out of the canon, and today it is a drink most people have never heard of - a genuine lost classic. Which makes finding a personal variation of it in a family notebook all the more special.

The grandfather’s variation

Our reader’s version is a specific, personal take on the Bronx, and a clever one. It makes two notable changes from the textbook recipe. First, it uses only French (dry) vermouth, rather than the classic mix of sweet and dry - giving a drier, crisper drink. Second, and more distinctively, it adds a little raspberry syrup in place of the usual sweetness, which lends the drink a soft pink blush and a gentle fruitiness.

That raspberry twist is what makes it a house recipe rather than a straight Bronx, and it is easy to see why the reader’s wife and her friends are fond of it: it is a pretty, pale-pink, lightly fruity, dry-but-approachable gin cocktail - sophisticated and a little old-fashioned in the best way. Grandfather knew what he was doing.

How to make it today

Here is the recipe translated into modern measures, staying faithful to the original:

• 30ml gin
• 30ml dry vermouth
• 2 dashes (about 5ml) raspberry syrup
• 2 dashes fresh orange juice

Method. Add everything to a mixing glass with plenty of cracked ice. Stir well until chilled, then strain into a chilled cocktail glass. The drink comes together as a pale, blushing pink, dry and delicate with a whisper of raspberry and orange. Garnish, if you like, with a twist of orange or a single raspberry - though the original specifies none.

A few modern notes. Use a good dry vermouth and keep it fresh (refrigerated after opening), as it is half the drink. “Dashes” are small - this is a dry, gin-and-vermouth-forward cocktail, not a sweet fruity one, so resist the urge to add more syrup and juice than specified. And a classic London Dry gin suits it beautifully, letting the vermouth and the faint fruit play around the juniper.

The takeaway

Our reader’s grandfather’s cocktail is a genuine piece of history: a personal, pink-tinged variation on the Bronx, one of the great gin cocktails of the early twentieth century, preserved in a handwritten bartender’s formula book. It is real, it is lovely, and it is a reminder that some of the best drinks are the ones that quietly disappeared and wait in old notebooks to be rediscovered. Dry, delicate, and blushing pink, it clearly deserves its place in one family’s repertoire - and now, perhaps, in yours. Thank you to the reader who shared it. If you have an heirloom gin recipe of your own, we would love to see it.
