Mah-Jonng Cocktail – Classic 1920s Gin, Rum & Cointreau Mix

A drink with roots in the 1920s, the Mah-Jonng is a crisp, spirit-forward cocktail that layers gin’s botanicals, the warmth of dark rum, and the bright citrus lift of Cointreau.

Background

The Mah-Jonng first appeared in print in the late 1920s, during the height of Prohibition and the global craze for the tile game mah‑jongg. Named after the popular pastime, this cocktail was created by bartender Willie Dale and later recorded in Harry McElhone’s Barflies and Cocktails (1927). With its unusual pairing of gin and rum, balanced by the orange liqueur Cointreau, it stood out among the era’s many spirit-forward inventions. Today, it remains a fascinating snapshot of vintage cocktail culture.

What You’ll Need

• Gin – The crisp, juniper-led backbone that gives the drink structure and freshness.
• Dark Rum – Adds richness, depth, and a subtle caramel‑spice undertone.
• Cointreau – A clear orange liqueur that balances the spirits with citrus brightness and a touch of sweetness.
• Ice & Cocktail Glass – Essential for proper chilling and serving.

A Winning Combination

What makes the Mah-Jonng stand apart is its bold yet balanced profile. The gin shines up front with clean, herbal botanicals, while the dark rum softens and warms the edges. Cointreau ties everything together, offering a bittersweet citrus lift that keeps the drink lively. It’s strong, elegant, and unmistakably a product of the cocktail renaissance of the 1920s.

Substitutions & Variations

• Rum Choices – Swap dark rum for light rum if you prefer a drier finish, or try spiced rum for extra complexity.
• Orange Liqueur Alternatives – Grand Marnier brings a deeper, brandy‑kissed flavor; triple sec offers a lighter, more straightforward citrus note.
• Gin Styles – A London Dry will give sharp clarity, while a modern botanical gin can introduce floral or herbal twists.
• Garnish Options – Traditionally served plain, but an orange twist or lemon peel works beautifully if you want a modern flourish.

Helpful Tips

• Chill the Glass – A pre‑chilled cocktail glass keeps the drink crisp from first sip to last.
• Shake Hard, Strain Clean – Because this drink is spirit‑only, a vigorous shake ensures the right dilution and temperature.
• Food Pairing – Pairs well with salty bar snacks, smoked nuts, or light canapés that echo its vintage character.
• Batching Trick – Multiply the recipe and store pre‑mixed in the freezer; just shake with fresh ice before serving to guests.
