Illegal - IBA Mezcal, Overproof Rum & Falernum Cocktail

The Illegal cocktail pairs smoky Espadín mezcal with a smaller measure of high-proof Jamaican rum, then balances that powerful base with lime, falernum, Maraschino Luxardo, and simple syrup. The result has smoke, funk, spice, citrus, and restrained cherry sweetness packed into a relatively small drink. Optional egg white can soften the texture without changing its core flavor structure.

Background

The International Bartenders Association includes the Illegal in its New Era collection. Its official specification combines Espadín mezcal and Jamaican overproof white rum with falernum, Maraschino Luxardo, lime, and simple syrup. The current IBA listing does not identify a creator or place of origin, so those details should not be presented as established history.

What You'll Need

Ingredients

• Espadín Mezcal - provides the smoky, earthy agave backbone.
• Jamaican Overproof White Rum - adds high-proof intensity and distinctive Jamaican rum character.
• Falernum - contributes sweetness, spice, citrus, and almond-like complexity.
• Maraschino Luxardo - adds a concentrated cherry and herbal accent.
• Lime Juice - supplies the fresh acidity needed to balance the sweet ingredients.
• Simple Syrup - rounds out the lime and strong spirits.
• Egg White - optionally adds a softer, lightly foamed texture.

If Espadín mezcal is unavailable, another joven mezcal is the closest practical substitute.

If Jamaican overproof white rum is unavailable, choose another flavorful overproof Jamaican rum rather than standard white rum if possible.

Equipment

• Cocktail shaker

Smoke, Funk, Spice and Citrus

Illegal gets much of its character from using two assertive spirits together. Espadín mezcal supplies smoke and roasted agave character, while a smaller amount of Jamaican overproof rum adds strength and aromatic funk.

Falernum, Maraschino Luxardo, and simple syrup form the sweeter side of the drink, but the substantial lime measure prevents those ingredients from taking over. That push between strong spirits, spice, sweetness, and acidity is what makes the recipe distinctive.

Substitutions & Variations

• Replace Espadín with another joven mezcal when necessary.
• Use another Jamaican overproof rum if the exact white-rum style is unavailable.
• Omitting the optional egg white keeps the drink completely within the published IBA specification.
• For the IBA's alternate presentation, serve the cocktail on the rocks in a traditional clay or terracotta mug.
• Avoid increasing the falernum or simple syrup casually. The drink already has several sweet components, and extra sweetness can quickly overwhelm the lime.

Helpful Tips

• Use fresh lime juice because acidity is central to balancing the falernum and syrup.
• Measure the overproof rum carefully. Its small quantity has a noticeable effect on both flavor and strength.
• Shake vigorously with plenty of ice for proper chilling and dilution.
• Chill the cocktail glass before straining.
• If using egg white, use pasteurized egg white and handle it according to food-safety guidance.
• The IBA specifies no garnish, so the clean presentation is intentional.
