Absinthe Cooler

Use 2:1 rich simple syrup for its listed portion.

Chill a highball glass before beginning the preparation.

Muddle fresh basil leaves in the base of a shaker to release their aromatic oils.

Add La Fée Parisienne absinthe, elderflower liqueur, freshly squeezed lime juice, and rich sugar syrup into the shaker.

Shake the mixture vigorously with ice to blend the flavors.

Fine strain the cocktail into the pre-chilled highball glass filled with fresh ice.

Top up with chilled Thomas Henry Ginger Ale to add effervescence.

Garnish with green grapes, elegantly resting them on the rim of the glass.
