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

Select and pre-chill a highball glass.

Prepare a garnish of fresh mint sprigs.

Lightly muddle the mint leaves in the base of a shaker just enough to release their aroma.

Add the absinthe, vodka, sugar syrup, and freshly squeezed lime juice to the shaker. Shake vigorously with ice.

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

Top with lemon-lime soda and soda water in equal proportions.

Garnish with a bouquet of mint sprigs.
