Agua de Sandia

Nothing beats a cool, refreshing glass of watermelon water on a hot day! Known in Mexico as agua de sandía, this light and naturally sweet beverage is a staple in Mexican households.

Glass of Watermelon Water

Any time you see a drink is called “agua de…” it is a type of drink known as an agua fresca . “Agua fresca” translates to “fresh water,” and this version is made by blending fresh watermelon with water and a touch of sugar.

Other examples of aguas frescas would be: “Agua de piña” (pineapple water), “agua de pepino” (cucumber water), “agua de melon” (cantaloupe water). You get the idea :)
