If using a salted or sugary rim, rub a lime wedge around the rim of the glass and dip it into salt or sugar.

Blend the cucumber slices in a blender until smooth. For a smoother texture, strain through a fine-mesh sieve if desired.

In a shaker or pitcher, combine the cucumber purée, fresh lime juice, orange juice, and agave syrup or honey. Stir until well mixed.

Gently stir in the sparkling water or soda.

Fill the prepared glass with ice and pour the cucumber mixture over the ice.

Garnish with cucumber slices and fresh mint leaves.

Feel free to adjust the sweetness and lime juice to your preference. Enjoy your drink!
