A mojito is one of my absolute favorite cocktails. It’s the quintessential summer drink. I was instantly hooked on mojitos after my first trip to Mexico. Since, I realized that not all mojitos are created equal.

Watermelon Mojitos are best made fresh, without a mix. Like all good things, a Watermelon Mojito requires just a few simple ingredients, yielding the most amazing summer flavor.

What is in a Watermelon Mojito?

A mojito is typically made with mint, sparkling water, rum, simple syrup and lime juice. This Watermelon Mojito recipe offers a simple twist that’s full of summer flavor!

  • pureed watermelon or juice
  • sparkling water or club soda
  • mint leaves
  • simple syrup (aka as mojito syrup)
  • rum
  • optional: freshly squeezed lime juice

The combination of juice and rum is irresistible! It’s perfect for Cinco de Mayo parties, barbecues, poolside or a day on the water. A watermelon rum cocktail is just what summer ordered!

Sweet Mint

By summer, mint is growing abundantly in our garden. I incorporate it into some of our favorite dishes like this Cherry Tomato Pasta, but especially enjoy it in summer cocktails. Mint adds so much flavor and makes a beautiful garnish as well.

If you plant just one herb, plant mint. It is extremely easy to grow, very forgiving, and a great addition to so many recipes. It also keeps bugs at bay! Plant mint in a pot or container. You can bury it in the ground if you prefer. Otherwise mint can overtake your garden because it quickly multiplies.

Do You Need a Mojito Muddler?

No, but I highly recommend one! A muddler is just $5 and great for making mojitos, guacamole and so much more! Plus, it makes you look like a skilled bartender. However, you can use any kitchen tool to mash the mint and release the flavor. The back of a wooden spoon makes a great alternative.

How to Make a Frozen Watermelon Mojito

Yes, you can make it frozen! Just add ice to the watermelon puree in your food processor. Blend with rum and simple sugar and pour over mint.
