Combine ingredients in a blender and blend until a uniform consistency is achieved. It may be necessary to add more ice or sweetness to adjust to your liking. Pour into wine glasses or, if poolside, plastic goblets. Garnish with lime wedges and serve with a straw.

*Cantaloupe juice: The preferred method is to use a pulp extractor style juicer. If you do not have a juicer, cut the melon into 1-inch cubes and blend with the smallest amount of water possible in a high-speed blender until the fruit is liquefied. Strain through a fine mesh strainer and allow to settle. Skim off the foam before using the remaining juice.
