Spicy Watermelon Cocktail Ingredients

  • Altos Plata: 100% agave, voted as the best tequila for margaritas by bartenders worldwide. It’s unaged, mellowed out and got the purest flavors making it ideal for complementing the rest of the ingredients in this watermelon tequila cocktail.
  • Ancho Reyes: These bring the spice to the party.
  • Basil Syrup: Brings a sweet herbal flavoring to this refreshing watermelon tequila cocktail.
  • Watermelon Juice: The main ingredient! We recommend fresh watermelon juice for this recipe, but store-bought also works as long as there is no added sugar.

Tips to Make the Best Tequila and Watermelon Recipe

Here are some tips that will bring your cocktail to heaven:

  • Get a ripe and juicy watermelon: This means you should choose one with a good yellow spot. That’s usually an indication that it’s been sun-ripened.
  • Plan ahead: A little planning is needed, so set aside some time for preparation. However, once you’ve prepared all of the ingredients, you’ll only need 5 minutes!
  • Serve immediately: The longer it sits, the more it will separate. If it does separate, it’s not a big deal; simply mix it with a spoon.
  • Salt rim: This is entirely optional and based on personal preference. To salt the rim, run a lime wedge around the edge of the glass and dip into a shallow layer of salt. You can also add some chili or Tajin if you like it extra spicy and colorful.
  • Chill the glass: This cocktail tastes best when served with ice or in a chilled glass.
  • Step it up with a chilled watermelon garnish: Chilled watermelon wedges serve as large ice cubes and keep the cocktail cold for longer. A chilled watermelon wedge also looks great as a garnish!

How Can I Make the Basil Simple Syrup?

The basil syrup gives this refreshing beverage a sweet herbal flavor. It’s also great in various cocktails, mocktails, lemonade, and frozen treats.

These are the ingredients you’ll need:

  • 1 cup water
  • 1 cup white sugar
  • 1 cup fresh basil leaves

Once you have them ready, proceed to:

  1. In a small saucepan, combine the water, sugar, and basil leaves.
  2. Bring to a boil, stirring until all the sugar dissolves.
  3. Reduce the heat and simmer for 1 minute.
  4. Remove from heat and let the syrup steep for about half an hour.
  5. Strain the syrup into a sterilized glass jar and let cool.
  6. Store in the fridge for up to 1 month.
