If you find you’ve bought a melon that isn’t the greatest, use it in smoothies, daiquiris, or Margaritas. And don’t waste the seeds and juice—make melon seed aguas frescas....

This recipe makes 1 blenderful; for 16 people, you’ll probably need about 4 batches.

Literally “fresh waters,” aguas frescas are Mexico’s answer to a hot day.
