Agua Fresca is a traditional Mexican drink, usually made with a combination of fruits and/or vegetables mixed with sugar and water to make a light, refreshing non-alcoholic beverage. My recipe is a simple, healthier version that replaces refined, processed sugar with organic, natural agave nectar, instead. To wrap it up, my watermelon agua fresca is made using only 5 ingredients: watermelon, agave, fresh mint and lime, and a pinch of sea salt. Plus a little filtered water!
