Cool and refreshing watermelon agua fresca, called agua de sandia. A perfect accompaniment to the comida, or mid-day meal and a much better option than soda.
1/8 medium watermelon. (To portion the watermelon, cut it in half lengthwise and then cut one of the quarters in half. Use 1 of the small pieces to prepare this drink.)
1 cup sugar
1/2 gallon water
8 mint or spearmint leaves
