This watermelon gin fizz is perfect for summertime sipping! Puréed watermelon is muddled with fresh mint, floral gin, lime, and seltzer, and served on the rocks for the perfect summer cocktail.

I think we can all collectively agree that, as a society, we need a drink rn? Cool, glad we’re on the same page.

Luckily, I am getting plenty of bartending experience, because my Friday tradition is now to shake up a cocktail at approximately 4:55pm. Now that we aren’t necessarily hitting the bars, per usual summer tradition, I have become quite the home bartender. I even got a muddler, and I’m not using the handle of a wooden spoon anymore. Like, I’m basically a mixologist. 💁‍♀️

This particular watermelon cocktail is sweet, citrus-y, fresh, herbaceous, and slightly fizzy thanks to the addition of lime-flavored seltzer. If we’re being completely honest, I’m craving one at this very moment, but please don’t give me that “it’s 5 o’clock somewhere” spiel, because I turn 25 this week, and I’ve decided that’s too old for weekday morning cocktails, sorrynotsorry!

Whip up a batch of tortellini Caprese skewers and boozy sugared Prosecco grapes, and you have a lovely summer happy hour at home situation!

You’ll need some summery AF ingredients for this spritz but don’t worry. I’m not going to have you running around to every liquor store in town trying to find some artisan, small batch spirit. Just make sure you have a personal watermelon, simple syrup, lime juice, gin, mint, and lime seltzer.

To make simple syrup, just combine equal parts of water and sugar, mix, and bring to a boil for about two minutes. Cool, and store in a bottle in the fridge until you’re ready to mix up a cocktail!

Juice the watermelon

Slice your watermelon into chunks, and add it to a blender or food processor. Blend until it’s completely puréed. Then, pour it through a strainer one or two times, until it’s a nice, smooth juice. (Don’t worry, a little pulp is ok!)

Feel free to use store-bought 100% watermelon juice instead if you want to skip a step!

For a pitcher cocktail

If you want to make this cocktail in advance, it’s super easy! Just multiply the ingredients by however many cocktails you are serving, and mix all of the ingredients except for the seltzer in a pitcher! Immediately before serving, pour the cocktail over ice, and finish with a splash of seltzer.

Picking the perfect watermelon

Picking a good watermelon is *essential* for the success of this recipe. You’ll definitely want a watermelon that is uber juicy and sweet. Look for one that feels heavy for its size, has a creamy yellow spot, and has lots of brown webs. You can also knock on it (yep, like a door). If it sounds hollow, it’s good to go!

Ingredients

  • 3 ounces fresh watermelon juice (1 personal or 1/2 regular watermelon)
  • 1/2 ounce simple syrup (optional)
  • 1/2 ounce fresh lime juice
  • Fresh mint
  • 2 ounces gin (1.5 oz. for a less boozy drink)
  • 1.5 ounces lime seltzer, to top
  • Melon, lime slices, and mint, for garnish

Instructions 

  • First, start by juicing your watermelon. Cut your personal (or 1/2 regular) watermelon into 1” chunks, removing and discarding the rind. Place the watermelon in a high-speed blender or food processor, and blend until completely pureed. Strain in a fine-mesh strainer 1-2 times to remove pulp and seeds (to desired smoothness). Refrigerate for up to four days until ready to use.
  • To make the cocktail, pour the simple syrup, lime juice, and 1-2 mint leaves in an 8-12 ounce cocktail glass, and muddle until the mint is fragrant, about 15 seconds.
  • Add the gin and 3 ounces of watermelon juice. Give it a stir, and then add ice. Stir until very cold, another 15 seconds or so. Top with the seltzer, and garnish with watermelon slices, lime, and mint. Enjoy!
  • To make a pitcher cocktail, multiply the ingredients by the number of servings you would like to make. Follow the same directions, muddling and mixing in a pitcher, but leave out the seltzer and ice. (Otherwise, it will get watery and flat!) Immediately before serving, pour the cocktail in individual cocktail glasses over ice, stir, and top with seltzer and garnishes.

Notes

The secret to those incredible craft cocktails is fresh herbs, fruit, and spices. For this cocktail, puree the watermelon & juice the limes fresh.
Add ice + seltzer right before serving. Otherwise, you’ll water down the cocktail.
You may not need the simple syrup in this cocktail depending on how sweet your watermelon is! If your watermelon is super sweet, leave it out. If your watermelon is a bit more watery, adding some simple syrup can help elevate the flavors. When in doubt, leave out the simple syrup, taste, and add it as needed!
