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 ripe watermelon.
Mint Leaves – Fresh mint leaves add 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 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, simple syrup is added to cocktails instead of sugar. It gets dissolved quickly in the drink. You can use make one and use it too.
Lime Juice – I highly recommend using freshly squeezed lime juice for the best flavor. Use bottled lime juice only if you have some serious explanation against not using freshly squeezed lime juice.
You can replace the lime juice with lemon juice.
White Rum – Traditionally, Mojito is made using white rum (light rum) but feel free to replace it with silver rum, vodka, or tequila.
Club Soda – Club soda adds that perfect amount of fizz. Make sure it is chilled. If you do not like fizz, you can use chilled plain or sparkling water instead.
You can also replace soda water with Sprite, ginger beer, or ginger ale but keep in mind that they are very sweet, so do not add any extra sugar.
Soda water can also be replaced with tonic water, pineapple juice, orange juice, or apple cider for a taste change.
Garnish the glass with a mint sprig, lime wedge, or a lime round.

How To Make Watermelon Mint Mojito
Preparation
Peel a 1 lb (500 g) watermelon and cut it into 1-inch cubes. You 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 blender jar or food processor jar 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 spoon 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 of mint leaves to a large pitcher and muddle them using a muddler or the end of a wooden spoon.

Add 4 tablespoon granulated sugar and ½ cup freshly squeezed 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 glasses and add 2-3 ice cubes, 2 lime slices, 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 sprigs. 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. This is the place where the watermelon rests on the ground. The splotch should be yellow.
2. The skin should be dark green with minor bruises (not deep ones). 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 in 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 the watermelon cubes 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 required and make it in a big pitcher for a gathering.
Please do not keep the muddled mint long, as it may become bitter with time.
This tasty Watermelon Mojito recipe can be made into an excellent mocktail (aka non-alcoholic cocktail). Just leave out the rum and sip away.
Storage Suggestions
Watermelon Mojito tastes best when made fresh. If kept for a long time, it loses its taste and freshness.
If you want to make it for a party or a get-together, mix the ingredients except for the rum and club soda and refrigerate them for up to 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.
