Change it Up:
Add the juice of two fresh limes into the mix for a tangier version (or like mentioned, just serve wedges on the side for people to squeeze in their own limey deliciousness).
Add mint! A sprig for each glass will do. Or if you really want to make it more potent, grab a handful of mint leaves and pulverize with the melon. Mint and melon are a great combo! The color of the juice will not be quite as clear, but it's a fun way to mix it up.
