Pin it This revitalizing drink combines the natural sweetness of seedless watermelon with cooling cucumber and bright lime juice. Fresh mint leaves add an aromatic finish, while sparkling water creates a delightfully fizzy texture. The optional low-carb sweetener lets you control the sweetness level to suit your taste.
Perfect for hot summer days, this hydrating beverage comes together in just 10 minutes with minimal effort. Simply blend, strain if preferred, and serve over ice for an instantly cooling treat that pairs beautifully with light salads or grilled seafood.
Last summer, my brother texted me at 7 pm on a sweltering Tuesday, needing a drink for impromptu guests on his new low-carb kick. I raided his crisper drawer, found a lonely watermelon half and some mint, and threw this together in five minutes flat. His friends kept asking for the recipe name, and I just kept calling it 'that pink thing' until we settled on something more dignified.
Ive started making this before dinner parties because people always drift into the kitchen, asking what smells so fresh. There is something about mint hitting the blender that announces 'something good is happening' better than almost any other ingredient. My neighbor now texts me whenever watermelon goes on sale, just to check if I am batching up a pitcher.
Ingredients
- Seedless watermelon: The sweetness varies wildly by season and melon, so taste a cube before blending and adjust accordingly.
- Fresh mint leaves: Do not use dried mint here, it tastes dusty and sad compared to the bright punch of fresh leaves.
- Small cucumber: English or Persian cucumbers work best since they have thinner skins and fewer seeds.
- Lime juice: Roll the lime on the counter before cutting to maximize the juice yield.
- Cold sparkling water: Add this right before serving to maintain the effervescence.
- Erythritol or preferred low carb sweetener: Watermelon is naturally sweet, so start with less than you think you need.
Instructions
- Blend the base:
- Add watermelon cubes, cucumber slices, mint leaves, and lime juice to your blender.
- Puree until smooth:
- Blend until completely uniform, with no visible chunks of mint or cucumber remaining.
- Strain if you prefer it clear:
- Pour through a fine mesh sieve into a pitcher, pressing gently with a spoon to extract all the liquid.
- Sweeten to taste:
- Add sweetener if using and stir until fully dissolved.
- Add the fizz:
- Pour in cold sparkling water and stir gently to combine without losing too much carbonation.
- Serve over ice:
- Pour immediately into glasses filled with ice and garnish with extra mint or a lime wedge.
Pin it This became my go to mocktail when I gave up alcohol for a month but still wanted something celebratory in a glass. There is a psychological shift that happens when you pour something fizzy and garnished, even without the buzz.
Make It Slushy
Freeze the watermelon cubes overnight, then blend them straight from frozen with the other ingredients. The texture transforms into something like a granita, no ice required.
Batch For A Crowd
Multiply everything by four and blend in batches, keeping the puree in the fridge until guests arrive. Add the sparkling water right before serving, pouring it into a large dispenser.
Flavor Twists
Once you have the basic method down, these variations keep it interesting all summer long.
- Swap half the cucumber for zucchini for a more neutral flavor that still adds body.
- Add a few basil leaves along with the mint for an herbaceous twist.
- Throw in a small pinch of salt to make the watermelon taste more vibrant.
Pin it Keep a bag of frozen watermelon cubes in your freezer all season long and you are never more than three minutes away from something that feels like a treat.
Recipe FAQs
- → Can I make this ahead of time?
-
For best results, prepare immediately before serving to maintain the sparkling water's fizziness. However, you can blend the fruit mixture up to 24 hours in advance and add the sparkling water just before serving.
- → Is straining necessary?
-
Straining is optional and depends on your texture preference. The fine mesh sieve removes pulp for a smoother, lighter drink, while leaving it unstrained provides more fiber and a thicker consistency.
- → What sweetener works best?
-
Erythritol, stevia, or monk fruit sweeteners blend well without aftertaste. Liquid sweeteners dissolve more easily, but granulated options work too—just ensure they're fully dissolved before adding sparkling water.
- → Can I use regular water instead of sparkling?
-
Absolutely. Still water creates a lighter, more subtle drink perfect for those who prefer less carbonation. The flavor remains refreshing and hydrating either way.
- → How do I make the slushy version?
-
Freeze the watermelon cubes for at least 4 hours or overnight before blending. The frozen fruit creates a thicker, ice-cold texture without needing additional ice, making it perfect for hot summer afternoons.
- → Can I double this recipe?
-
Yes, simply multiply all ingredients accordingly. You may need to blend in batches depending on your blender size, then combine everything in a large pitcher before serving.
