Sweet, tangy, and absolutely thirst-quenching, this beverage is one the whole family can enjoy.
4 cups watermelon, seeded and cubed (about 3 pounds)
1/2 cup water
24 mint leaves, divided
8 tablespoons super-fine sugar (adjust if too sweet when using a naturally sweeter watermelon), divided
4 very thin lime slices, halved into half moons, divided
Add the watermelon and the water to a blender, and puree until smooth. Divide the mint leaves, sugar and lime slices among 8 glasses and muddle the ingredients. Add ice to each glass and pour in the watermelon agua fresco. Stir and serve.
