Aguas frescas (Spanish for "fresh waters") are a combination of either fruits, grains, or seeds, and sugar and water, blended together to make a cheap and refreshing beverage. Although most common in Mexico, aguas frescas are also popular in Central America and the Caribbean. Some of the most popular flavors include agua de tamarindo (made with tamarind pods), agua de jamaica (made with hibiscus flowers), and agua de horchata (made with either rice or chufa nuts ).
