Monkey Gland – Gin, Orange & Absinthe Cocktail

The Monkey Gland combines London dry gin with orange juice, absinthe, and grenadine in one of the more distinctive cocktails to come out of the early 1920s. The result is citrus-forward and lightly sweet, with juniper underneath and a pronounced herbal-anise note from the absinthe.

A Paris Classic with an Unforgettable Name

The Monkey Gland is credited to bartender Harry MacElhone and appeared in his cocktail books in the early 1920s. Its name referenced the then-famous experiments of surgeon Serge Voronoff, whose controversial rejuvenation procedures became a major cultural talking point. Early published versions used much smaller amounts of absinthe and grenadine than the current IBA formula.

What You'll Need

Ingredients

• London Dry Gin – provides the dry juniper and botanical backbone. Another dry, juniper-forward gin is the closest substitute.
• Orange Juice – brings citrus sweetness, acidity, and body. Freshly squeezed juice gives the cleanest flavor.
• Absinthe – contributes the cocktail's defining anise and herbal character. Pastis can work in a pinch, although its flavor is not identical.
• Grenadine – adds pomegranate sweetness, balance, and color. A quality pomegranate-based grenadine works best.

Equipment

• Cocktail shaker
• Jigger or measuring tool
• Cocktail strainer
• Cocktail glass

Where the Monkey Gland Gets Its Edge

Gin and orange juice alone would make a fairly straightforward citrus drink. Absinthe changes the picture completely, adding a sharp herbal and anise note that cuts through the fruit, while grenadine rounds the edges with sweetness. The result sits somewhere between bright, botanical, and deliberately eccentric.

Substitutions & Variations

A different dry gin can replace London dry gin, but softer or heavily floral styles will change the balance.

Pastis or another anise-forward spirit can stand in for absinthe when necessary, though the result will not be identical.

For a historically inspired variation, use only a dash of absinthe and a teaspoon of grenadine rather than the larger modern IBA quantities. This creates a much drier drink in which gin and orange dominate.

Helpful Tips

Use fresh orange juice when possible. The recipe contains enough juice that its quality makes a noticeable difference.

Shake firmly with plenty of ice so the orange juice, syrup, spirit, and absinthe integrate properly.

Measure the absinthe carefully. Its flavor is assertive, and the current IBA version uses considerably more than early published formulations.

Chill the glass before straining so the drink stays cold without adding ice to the finished cocktail.
