Prepare the Cantaloupe: Carefully peel the cantaloupes, scoop out the seeds, and chop the vibrant orange flesh into manageable chunks.
Blend to Perfection: Working in batches, add the cantaloupe chunks to a high-speed blender.
Add a splash of the cold water to help it get started and blend until completely smooth.
Pour the purée into a large pitcher and repeat with the remaining fruit.
Sweeten and Chill: Once all the cantaloupe is blended, stir the honey into the pitcher until it's fully dissolved.
Add the ice cubes, give it a final stir, and let it chill in the refrigerator for at least 30 minutes to allow the flavors to meld.
Adjust and Serve: Before serving, give the agua fresca a taste. If it's too thick, stir in a little more cold water until it reaches your desired consistency.
Pour into glasses and enjoy immediately!
