Cut the cantaloupe in half, scoop out the seeds, and chop it into cubes.
Throw the cubes in a blender and blend until smooth.
Strain the puree through a fine mesh strainer into a bowl—press to get all the juice.
In a shaker, combine vodka, lime juice, simple syrup, and 2 ounces of cantaloupe juice.
Add ice and shake it up until it’s nice and cold.
Strain into a tall glass filled with fresh ice.
Top with chilled club soda.
Stir gently with a bar spoon.
Garnish with mint leaves, and if you’re feeling fancy, cantaloupe balls or a lime wheel.
