Watermelon cocktail with gin

The season for watermelon is short and sweet, so once it’s in: capitalize on this hydrating fruit! After making a watermelon margarita, tart, fruity, and a little salty, we just had to make more watermelon drinks. Meet the gin watermelon cocktail! It’s spirit-forward, botanical from the gin and tangy from lemon, and just sweet enough. It’s ultra refreshing, and that little watermelon wedge garnish? To die for. Here’s how to make this watermelon cocktail!

It’s naturally sweet!

This gin and watermelon cocktail is naturally sweetened: mainly by the fruit! It has a small amount of added sweetener: just 1/2 tablespoon honey or maple syrup for 3 to 4 drinks. The great thing about naturally sweetened drinks is that they taste vibrant and natural. Of course: feel free to go classic and use simple syrup instead!

How to make a watermelon cocktail

To make a watermelon cocktail, here are the basic steps (or jump to the recipe):

  • Make your own watermelon juice! Simply whiz watermelon in a blender, then strain it to weed out the particulates and get pure juice. Most blender have the cups marked on the side, so just throw in 2 cups of watermelon and blend it up. Then use a fine mesh strainer to pass through the blended watermelon to get the watermelon juice.
  • Muddle: Muddle (gently mash) lemon wedges and mint leaves in a cocktail shaker. Add watermelon juice, lemon, honey, and gin to a cocktail shaker.
  • Shake: Shake it up with some ice, and you’ve got one tasty watermelon cocktail!

The garnish makes it pop

With cocktail recipes, it’s all about presentation! This watermelon cocktail is made more perfect by the watermelon wedge garnish. Simply cut up little wedges of watermelon while you’re cutting it for the watermelon juice. They totally make the drink!

What cocktail shaker should I buy?

Cocktail shakers are inexpensive and absolutely worth snagging if you find yourself making lots of cocktails. A cocktail shaker quickly chills cocktails by shaking them against ice, then has a perforated lid so you can pour out the cocktail without pouring out the ice as well. Here’s the cocktail shaker we use: Favorite Cocktail Shaker | Amazon

If you’re in a pinch, you can actually use a glass mason jar instead of a cocktail shaker! Place the cocktail in the jar and fill it with ice. Put on the top and shake away! Pouring out the cocktail without the ice won’t be quite as elegant, but that’s ok, right?

What type of gin should I buy?

It doesn’t matter what type of gin you use for this watermelon cocktail: as long as it is high quality gin! The easiest way to tell if a gin is high quality? Don’t buy the cheapest gin you can find. Try to invest in a mid-price range gin: the drink will only taste as good as the gin you invest in!

You could also be on the lookout for local gin, if you have distilleries in your area. Here in Indianapolis, our friends over at 8th Day Distillery make a local gin that’s a fun local find.

Variations: watermelon vodka cocktail & watermelon mule!

Watermelon is perfect for blending into summer drinks: especially cocktails! Here are a few variations on this watermelon cocktail using vodka instead of gin:

  • Watermelon Mule Why make a Moscow mule when you can make a watermelon mule? This bubbly drink stars vodka, watermelon juice, and ginger beer.
  • Watermelon Vodka Cocktail This watermelon vodka drink is similar to this gin cocktail but uses watermelon juice, vodka and tangy lime.

    What a gorgeous recipe! What to do on a hot afternoon in Australia with lots of watermelon? …….. this is a very delicious (and moreish) cocktail. I had lychee juice which I substituted for the honey, and the result was perfumed deliciousness!

    Thankyou, will definitely be making this again :)
