This Watermelon Agua Fresca is the refreshing drink for summer. The pink hue feels fancy, but with three ingredients (watermelon, coconut water, and lime juice), it’s shockingly simple. And sooo delicious and hydrating.

Watermelon Lime Agua Fresca - Zero added sugar, all-natural, totally refreshing, and only three ingredients - fresh pureed watermelon, coconut water, and lime juice.

The Story Behind the Recipe

Whenever I host a Mother’s Day meal, I naturally turn to pink. Pink everything. Pink flowers. Pink dishes. And, of course, pink food and drink.

I mean, what better color to celebrate women everywhere?! It’s the most feminine color around. And so many delicious foods lend themselves naturally to this, the chickiest of hues. Like strawberries. And raspberries. Radishes, potatoes, even some onions. And of course – of course! – watermelon. The queen of melons, she’s sweet, she’s succulent, and she’s as rosy as they get.

You know where I’m going with this. Watermelon agua fresca is indeed the perfect shade of pink for Mom’s Day.

And you know what else is awesome about this stuff? Unlike most agua frescas, this one has zero sugar added! None! It doesn’t need it.

Watermelon Agua Fresca Ingredients

Such a simple list of ingredients – exactly 3 ingredients, to be exact! We’ve got:

  • Watermelon, of course – pureed and strained.
  • Coconut water – hydrating, naturally sweet, and perfect with watermelon
  • A squeeze of lime
Watermelon Coconut Agua Fresca - Zero added sugar, all-natural, totally refreshing, and only three ingredients.

The natural sweetness in both the watermelon and the coconut water are plenty to make this perfectly drinkable and completely refreshing. The perfect summer drink. Light, hydrating, delicious – but not cloying.

If you really, really want yours a little sweeter, just stir in a little sugar until it dissolves, but I uphold it truly doesn’t need any. I also don’t find full-on sugar soda or heavy fruit juices refreshing – especially in the heat of summer – so this watermelon agua fresca is what I’ll be sipping on instead. With a decorative straw. It makes all of the difference.
