Hibiscus Watermelon Agua Fresca Recipe - Quick and easy!

There are few things are more refreshing than an agua fresca (which literally means cool water, appropriately enough).

Typical agua frescas are non alcoholic drinks, slightly sweetened and served chilled. While fruity agua frescas are most common, non-fruit flavors like horchata, tamarind, and hibiscus can also be categorized as agua frescas.

Not only are they ridiculously refreshing, they are also ridiculously easy: simply blend your fruit with water, strain, and add sweetener and acid to taste.

Fresh Watermelon Agua Fresca recipe with Hibiscus and Lime

Some of my favorite agua fresca flavors include watermelon and hibiscus (also called jamaica flowers), and I’m often torn which one to order. It’s a tough choice, so I figured, why not have both?

That’s exactly what I’ve done here, infusing a classic fresh watermelon agua fresca with a tart and tangy hibiscus tea. Add a touch of sugar and a splash of lime and you’ve got yourself one lovely summer refreshment.

Hibiscus and Fresh Watermelon Agua Fresca

Dried hibiscus flowers are available at many international or Mexican grocers, you can also buy it online. Once you’ve acquired the flowers, all you need to do is steep in hot water for about 10 minutes, then strain. I kill two birds with this step and turn the hibiscus tea into a sugar syrup to sweeten the drink at the same time. (It’s a similar process to my Spicy Cantaloupe Agua Fresca – which steeps the habanero peppers in the sugar syrup to infuse the drink with sweetness and spice.)

Of course, if you’re wanting a classic watermelon agua fresca instead, you can simply leave out the hibiscus flowers. Making a sugar syrup is my preferred way of sweetening the drink anyway, as you can be assured the sugar will be fully dissolved.

Might I recommend keeping a pitcher of this in the fridge at all times this summer? It’s not hard to do, considering this recipe only uses about 1/4 of a regular sized watermelon; so you might benefit from a double or triple batch.
