Cucumber Watermelon Margarita

Making the fresh cucumber simple syrup

The first step in making these refreshing Cucumber Watermelon Margaritas is making the Cucumber Simple Syrup. To make the syrup, you will need:

  • A medium cucumber, peeled and chopped into small pieces.
  • 1 cup organic cane sugar. I highly recommend organic cane sugar over standard granulated sugar for all my simple syrups. It’s got a better flavor, and more balanced (not cloying) sweetness.
  • A cup of water.

To make the syrup, simple add all 3 ingredients to a small saucepan, and bring to a boil. When boiling, reduce to a simmer, and allow to cook 15 minutes. After the 15 minutes, turn off the heat and allow to cool completely. Leave the cucumbers in there! This way, the flavor can fully develop. Once cooled, strain the syrup into a mason jar, and discard the cucumbers.

The syrup will keep about a week in the fridge, and yields about 3/4 cup!

Making the margaritas

Once your cucumber syrup is ready to go, all you need to make these cocktails is:

  • The Cucumber Simple Syrup.
  • Some fresh or store bought watermelon juice. To make your own watermelon juice, cut up a watermelon and blend it up (in batches if it’s large). Strain through a fine mesh sieve, and voila- you’ve got natural and delicious watermelon juice! I also love Simply Watermelon!
  • Some good silver tequila. I love Espolon and Blue Nectar!
  • 1 cup Powell & Mahoney Classic Margarita Mix. It’s all-natural, and isn’t loaded down with artificial tasting additives.
  • The juice of 1 lime.

Add all ingredients to a large mason jar or cocktail shaker, and shake well.

Garnishing and serving the Cucumber Watermelon Margaritas

When your margaritas are ready to go, it’s time to garnish and serve!

This recipe yields about 4 smaller margaritas (or 2 BIG margaritas). I love to serve them with a lime salt rimmed glass, and some cucumber or lime slices.

To make the salt rim, Mix about 1 tbsp coarse salt to the zest of one lime. Scale up if making more margaritas. Another fun way to garnish the glasses that I love is to use a Himalayan pink salt or violet salt with the lime zest to rim the glass. It adds a beautiful pop of color!
