How this recipe came to be

Not in the mood for story time from 2019? Feel free to jump straight to the recipe at the bottom!

In light of our upcoming honeymoon, I’ve been trying to lose a few pounds and I’ve taken to counting calories. Not my idea of a good time. BUT… it works.

One of the things that’s kind of gone by the wayside is my favorite wine. A 5 ounce pour of Riesling is a whopping 120 calories, so it’s hard to convince myself that it’s worth it when the math is staring me in the face.

That’s not to say this is a permanent thing, because it’s definitely not. I just want to feel a little bit better about the shape I’m in when we embark on our trip to Hawaii where I’ll be wearing a whole lotta shorts and bathing suits. By the time we get back, I’ll have eaten my weight in mangoes and papayas, so it’ll all even out.

Slices of watermelon

As a substitute to my occasional glass of wine, I decided to go the route of agua fresca – specifically, this watermelon agua fresca.

I drink a crapload of water on a daily basis, but I need something with flavor in there sometimes to break it up so I don’t feel like a giant water balloon. And since it’s watermelon season (and I have entirely too much of it on hand because I always think I’m going to eat it quicker than I do), it seemed like the right choice.

How to make watermelon agua fresca

You only need three ingredients and a blender (aff link) to make this. No, seriously – that’s it. The longest part of the process would be cutting up your watermelon, if it’s not already cut into cubes. 

Just dump the watermelon, some coconut water, and the juice of one lime into a blender (aff link) and let it do its magic. Less than a minute later, you can be relaxing with a glass of refreshing agua fresca, and relishing the fact that it’s almost half the calories of that glass of wine I’m resisting.

To strain or not to strain

You’ll end up with a little foamy topper when you pour it into their glasses, and it’s honestly one of my favorite parts. However, as it sits (which I would hope it wouldn’t be doing because you’d be sucking it down) it can start to separate and you’ll need to give it a little stir.

If that bothers you, can you strain the mixture through a fine mesh sieve (aff link) to get rid of any potential pulp from the watermelon and lime before serving.

But like I said… I really like it, so I don’t strain mine.

Give each glass a little lime wedge garnish, too. The color of the drink is already pretty, but who couldn’t use a little more pizzazz?

Straw or no straw?

And if you’re the type that enjoys straws, add a colorful one. There’s absolutely nothing wrong with metal straws (I own them), but it will sort of ruin the aesthetic we’re going for. 

We’re looking for a colorful, light, fruity, refreshing drink – not a cold, militarized, unsympathetic glass confusing color schemes.

Although, I guess we do want it to be cold… but we’re talking temperature, not attitude. And yes, my drinks have attitudes. Thank you very much.

Add a garnish

Add a lime wedge to the edge of the glass for a pop of color and extra flavor.

Feeling crazy? Add a gigantic slice of watermelon as garnish and see what your guests say. I dare you.
