In a cocktail shaker or mixing glass, place the fresh mint leaves (6) and cucumber slices (3). Add the simple syrup (0.5 oz) and gently muddle 6–8 times to release mint oils and cucumber juice without pulverizing the mint.

Add spirits and juices

Add the vodka (1.5 oz) and freshly squeezed lime juice (0.75 oz) to the shaker. Add the cranberry juice (1.5 oz). Fill the shaker with ice (about 1 cup) until roughly 3/4 full.

Shake

Secure the shaker lid and shake vigorously for 10–12 seconds until the outside of the shaker is frosty and well chilled. This chills and slightly dilutes the cocktail, integrating the muddled flavors.

Strain and build

Double-strain the contents into a highball or Collins glass filled with fresh ice to remove mint fragments and cucumber bits. Pour the shaken mixture over the ice.

Top and finish

Top the drink with club soda (2 oz) and gently stir once with a bar spoon to combine without losing fizz.

Garnish and serve

Garnish with a lime wheel (1) on the rim and a sprig of mint (1). Optionally slap the mint sprig between your palms first to release aroma. Serve immediately.
