Jump to Recipe

This week is officially the First Day of Summer. But here in South Texas, it’s been summer since the beginning of May. We’ve been trying to find ways to cool ourselves off while we enjoy the outdoors. We enjoy fresh cold drinks such as strawberry mojitos, so decided to try one I’d heard of before called agua fresca.

Our favorite fresh fruit in the summer is juicy watermelon so we often buy a whole melon and cut it up to munch on for the next few days. It’s perfect for hot summer days when the boys come in from playing outside since it’s cool and refreshing. Plus it’s a perfect way to help keep them hydrated since watermelon is 91% water.

Now and then we have more watermelon than we can eat. I don’t like it when it’s too hard but also don’t like it to get squishy. There are about one or two days of optimal watermelon eating for me. The boys will eat it when it isn’t quite as ripe, but it still often leaves us with extra.

I’ve mentioned before in my updates about the garden that we have an overabundance of mint leaves and have been searching for something to make with it. We like to make mojitos, but those take a few ingredients that we don’t always have in the pantry unless we plan on it.

So one evening recently, Justin started looking for ideas to use both the watermelon and mint. I told him to search for an agua fresca recipe and we had everything so decided to give it a try. The boys were at my in-laws for the night so we wanted an adult drink since we were “off duty”.

So we added a bit of rum to the drink, and it was delicious. And dangerous. I couldn’t taste the rum at all in the drink, but I could feel it a little bit later! But please, drink responsibly and only offer to those 21 years of age or older. 

Agua Fresca Options

While we made our original recipe with only watermelon, you could add a lot of other fresh fruit to the mixture. 

  • Add fresh pineapple for vibrant tropical pineapple agua frescas
  • Add orange or lemon juices for a different flavor
  • Mix in cucumber for cucumber agua fresca
  • Dice up a sweet prickly pear to juice into the drink
  • Tangy pomegranate, flowery guava, or tart hibiscus adds a great flavor to the easy cocktail

Agua Fresca Step by Step


  • 5 cups watermelon (chopped and seeded)
  • 1/8 cup mint leaves
  • 1/4 cup granulated sugar
  • 1/8 cup lime juice
  • 1/4 cup rum
  • 2 cups water


This drink is very easy to make, as long as you have a blender, you can have some spiked agua fresca. All of the ingredients are tossed in a blender, pureed until smooth, and served in a cup over ice.

To make regular agua fresca, you want about 5 cups of watermelon, without the seeds, chopped into pieces that will blend well. The pieces don’t have to be uniform in size, though, just small enough to fit in your blender. Add in 1/8 cup of mint leaves, 1/4 cup of sugar, and 1/8 cup of fresh lime juice. Then, to spike it, add about 1/4 cup of rum. Of course, if you want it stronger just add more rum or less for a weaker drink.

Once you have blended everything, you’ll want to use a sieve or mesh strainer to pour the drink through so you don’t have chunks of watermelon in your drink.

Add 2 cups of water and stir; then your drink is ready to serve! Since it isn’t going to be cold, I suggest serving it over ice or chilling the drink before serving.

If you want to get really fancy, add a sprig of mint to garnish the cup, and you could also do a sugar-rim on the cup (which we didn’t do this time).
