1 cantaloupe, halved and seeded
1/2 cup white sugar, or more to taste
2 cups milk
6 cups cold water, or more as needed
Shred the cantaloupe into a large pitcher using a fork, making sure to catch all the juice and pulp. Stir in sugar, mashing any large pieces of cantaloupe. Stir in milk and water, adding enough to fill the pitcher. Serve cold.
