If I made a list of my top 10 summertime recipe favorites, this cocktail would make my list. The mint simple syrup made with fresh mint leaves adds sweetness to the drink. A squeeze of fresh lime adds a little citrus flavor. You’ll need to prep the watermelon juice and mint simple syrup first, but both are quick to make. The fantastic thing about this cocktail is that you can easily turn it into a non-alcoholic mocktail. Omit the gin and add a splash of club soda or seltzer water.

What are the Benefits of Watermelon?

Watermelon is filled with antioxidants and lycopene. In fact, watermelon has more lycopene than raw tomatoes. Besides being very hydrating, it’s full of antioxidants and fiber.

What Equipment Do I Need to Make Watermelon Juice?

You’ll need a blender. The watermelon cubes are pureed in the blender for about 20 to 30 seconds. If you want the juice to be smoother, you can pour it through a fine sieve. I did this when I made the cocktail.
