How to make it

  1. Wash and inspect ten sound basil leaves.
  2. Add basil, gin, lemon and syrup to a shaker with ice.
  3. Shake vigorously to mix, chill and extract basil aroma.
  4. Strain through a cocktail strainer and fine sieve into a chilled coupe.

Why it works: Basil contributes aroma and colour, not a known measured liquid volume. Fine straining is a disclosed service choice to remove leaf fragments.

Common mistakes, useful fixes

Brown aroma

inspect leaf condition.

Fragments

use clean fine straining equipment.

Different basil

trial the variety rather than assuming identical flavour.

Serving the guest

Dietary and product checks

Check exact products, declared allergens and cross-contact controls before service.

Variations

Where does the Gin Basil Smash come from?

Origin: Origin not yet verified in this edition. (Origin not yet verified in this edition)

This modern herbal sour demonstrates that an aromatic ingredient need not be a liqueur or syrup. Basil is shaken with the citrus base, then removed for this served-up version. A separate history check is still needed before teaching a precise creator or date; the lesson does not invent one.

Gin Basil Smash questions

Are ten basil leaves included in the liquid percentage denominator?

No. They are listed separately because their extracted contribution is unmeasured.

What preparation detail matters for this order?

Basil contributes aroma and colour, not a known measured liquid volume. Fine straining is a disclosed service choice to remove leaf fragments.

From a recipe to a repeatable skill

Learn the method behind the order.

Gin Basil Smash is a required study in Essential Cocktails & Bar Foundations, module 4: Fresh ingredients and finishing. Compare basil extraction with mint handling; filter leaf fragments.
