So, I finally made the agua fresca. The recipe is posted (See "Watermelon Agua Fresca"), but I opted to use cantaloupe and mango instead of watermelon, which was pretty good. I recommend letting the drink sit in your fridge for 24 hours; the flavors have a chance to blend. Two out of three Mather-Greenwoods voted thumbs up on this one. My son was the only hold out: "I don't yike it." I'd make this one again for sure. And it would be super fun for a party.
