About This Recipe
Made using fresh watermelon juice, mint leaves, sugar, lime juice, white rum, and club soda, Watermelon Mojito is a refreshing fun cocktail that is a breeze to make using a few simple ingredients.
It has the perfect sweetness from watermelon, tanginess from lime, and the fizz from the club soda. For me, this is a perfect summer cocktail to serve for Sunday brunches, potlucks, or lazy summer afternoons by the pool.
This Watermelon Mint Mojito is so colorful and vibrant that no one can say no to it. Plus when at home, you can control the amount of sugar that goes into making it.
If you want to make a non-alcoholic version for kids or people who don’t drink alcohol, just skip adding the white rum and you have a delicious mocktail ready.
You can also add other summer fruits or vegetables such as strawberry, raspberry, cucumber, cherry, etc to this cocktail for that added twist.
Ingredients

Watermelon – Your cocktail will be as good as your watermelon. Choose the best that you can get. To save time, you can buy an already cut watermelon.
Mint Leaves – Mint leaves adds a nice refreshing flavor. Replace them with basil leaves for a change in flavor.
Sugar – Adjust the sugar according to your taste. If the watermelon is very sweet, you can skip adding any extra sugar. Sugar-free substitutes like stevia or monk fruit also work fine.
You can also opt for natural sweeteners like honey, maple syrup or agave nectar.
In restaurants & bars, sugar syrup is added to cocktails instead of sugar. It gets dissolved quickly in the drink. You can use it too. Check out my recipe to make simple syrup at home.
Lime Juice – I highly recommend using fresh lime juice for the best flavor. Use bottled lime juice only if you have some serious explanation again not using freshly squeezed lime juice.
White Rum – Traditionally, Mojito is made using white rum but feel free to replace it with vodka or tequila. There should be some perks of making it home, right?
Club Soda – Club soda adds that perfect amount of fizz. Make sure it is chilled. If you are not someone who likes fizz, then you can use chilled plain or sparkling water instead.
You can also replace club sod with sprite but keep in mind that sprite is very sweet on its own, so do not add any extra sugar.

How To Make Watermelon Mint Mojito
Preparation
Peel a 1 lb (500 g) watermelon and cut it into 1-inch cubes. We need approximately 0.6 lb (300 g) of cubed melon. Chill the cubes for a few hours before making the drink.
Add watermelon cubes to the large jar of a blender and blend until smooth. Don’t bother if the watermelon has a few seeds. We are going to strain the juice anyway.


Strain the juice through a fine-mesh strainer in a bowl or a pitcher. Press with the back of a ladle to get maximum juice. Discard the pulp. Straining the juice gives a clear drink.


Wash the mint leaves and juice the limes. Cut 2-3 limes into roundels.
Gather all the remaining ingredients like sugar, chilled club soda, and lime juice.
Make The Cocktail
Add ¼ cup mint to a pitcher and muddle it using a muddler or a wooden spoon.

Add 4 tablespoon fine sugar, and ½ cup lime juice to the pitcher and stir until the sugar is dissolved.

Stir in 8 fl oz (1 cup) white rum and watermelon juice.

Take 4 tall serving glasses and add 2-3 ice cubes, 2 lime rounds and 2-3 mint leaves to each of them.

Fill half of the glasses with the watermelon juice mixture and then top with club soda. Garnish with a watermelon slice and mint leaves. Serve watermelon mojito immediately!


Note – You can add a few frozen watermelon cubes to the glass. They will slowly melt and keep the drink cooler for a long time.
Frequently Asked Questions
Choose a ripe and juicy watermelon to make this Mojito. There are a few tips to check if the watermelon is good.
1. There should be a splotch at the base of the watermelon. This is the place where watermelon rests on the ground. The splotch should be yellow in color.
2. The skin of the watermelon should be dark green with a few small bruises (not deep bruises). It should not be perfectly smooth.
3. It should feel heavy for its size.
1. Cut off the ends of the watermelon.
2. Cut it into half crosswise.
3. Using a sharp knife, remove the rind.
4. Remove the white part as well.
5. Cut the half into 4 parts.
6. Then chop into cubes.
I used Bacardi Carta Blanca but you can use any mid-range white rum like Captain Morgan, Appleton, etc.
Pro Tips By Neha
Make sure all the ingredients are chilled for a few hours. It will be great if you chill the serving glasses too.
This recipe can be easily doubled or tripled. Scale it as per your requirement and make it in a big pitcher for a gathering.
Do not keep the muddles mint for long as it may turn bitter with time.
Storage Suggestions
Watermelon Mojito tastes best when made fresh. If kept for long, it loses its taste and freshness.
If you want to make it for a party or a get-together, then mix the ingredients except for the rum and club soda and refrigerate the mixture for upto a day. When ready to serve, add the white rum, ice cubes, and soda and serve immediately.
Make sure to stir the Watermelon Mojito before pouring it into the glasses.
