Making the most of the your summer produce haul can be hard to do if you overbuy at the farmer’s market like I do every single time I am there. Of course there are always the “eat it as fast as you can” approach, but sometimes it’s nice to mix it up! Watermelon is always a favorite in our house, the kids will devour it non stop. It’s not a bad thing by any means. Watermelon is very hydrating, so I have no qualms about just mowing down slice after slice. There are times it’s nice to make it into a refreshing drink like this Watermelon Guava Agua Fresca, too!

What is Agua Fresca?

Agua Fresca means “Fresh Water”, and you can mix and match fruits, grains, flowers, along with sugar and water to make it. Fruit is very common, along with lime juice, agave, and a little salt to balance the flavors. You can use other sweeteners if you choose, depending on your taste and preference.
