How to buy sweet and ripe watermelon?

Buying sweet and ripe watermelon is really important when you are making watermelon dishes. To check if a watermelon is ripe, you need to check for the weight, color, and sound. 

Ripe watermelon would be heavy in size and would have a creamy yellow splotch at the place where it rests on the ground. Also, tap or knock the watermelon and if it sounds hollow then it is ripe and juicy.

How to make Watermelon Mojito?

Making watermelon mojito is super simple. You just need to make watermelon juice and then mix it with other ingredients.

This is how a traditional alcoholic mojito drink is made in 4 simple and easy steps:

Step 1:

Blend watermelon cubes until smooth. Strain the juice using a mesh strainer.

Step 2:

Add lime juice, white rum, icing sugar, muddled mint leaves, and lemon slices. Stir.

Step 3:

Add lime slices, mint leaves, ice cubes to a glass. 

Step 4:

Pour watermelon mojito. Top with soda water. Garnish with a lime and watermelon slice. Enjoy chilled. 

How to store Watermelon Mojito?

Watermelon mojito tastes great when made and served fresh. So if you are planning to make it for a party or get-together, then you probably want to store it. 

In that case, make the mojito without mint leaves, lime slices, and white rum. At the time of serving, add white rum, mint leaves, and lime slices. This way it would taste fresh and delicious.

Can I make Watermelon Mojito without sweetener?

For a healthier version of this Watermelon Mojito, you can replace sugar with agave nectar. A ripe watermelon is generally sweet, so you can also entirely skip the sweetener.
