Elixir

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

Chill a highball glass to prepare it for serving.

Select fresh mint sprigs to use as a garnish.

Gently muddle mint leaves at the bottom of a shaker just enough to release their aroma.

Add the herbal liqueur, rich sugar syrup, and freshly squeezed lime juice to the shaker.

Add ice, then shake the mixture well.

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

Top up with soda water and give it a brief stir.

Serve with a straw and garnish with the prepared mint sprigs.
