Cut cantaloupe into bite size cubes.
Add the following to a blender: bite size cantaloupe, sweetened condensed milk, evaporated milk and water. Blend on high speed for about 45 seconds to one minute. Since there is a large volume of liquid that is blended with the cantaloupe, you may need to split the ingredients in half and blend in two batches.
Use a fine mesh strainer to strain the cantaloupe pulp that did not full blend. Discard the excess pulp that cannot be strained. Once you make this recipe as often as I do, you will notice that the ripest cantaloupes will leave very little excess pulp after straining.
Once you are ready to serve the drink, add plenty of ice and garnish with mint, blueberries or cantaloupe. Store the remaining agua fresca in the refrigerator. Mix the beverage with a large spoon before serving again. I hope that you enjoy this Agua de Melon as much as I do. Although it is simple, it is a classic Mexican agua fresca.
