Begin by selecting a ripe cantaloupe and a firm cucumber. Slice the cantaloupe in half, scoop out the seeds, and dice the flesh into manageable pieces.

In a blender, combine the diced cantaloupe and cucumber. Blend on high for about 30–40 seconds until the mixture is smooth and silky.

Pour the blended mixture through a fine mesh sieve into a pitcher. Use a spatula to press down on the pulp, extracting all the liquid.

Once mixed, add freshly squeezed lime juice to the pitcher. Stir gently to combine for about 15 seconds.

Fill tall glasses with ice cubes. Pour the strained mixture into the glasses until they are approximately three-quarters full.

Top each glass with sparkling water or club soda. Gently stir to mix the layers slightly without losing the bubbles.

Garnish each drink with fresh mint leaves and a cucumber slice on the rim of the glass.
