  • 1 1/2 ounces tequila
  • 1/2 ounce Grand Marnier
  • 1 1/2 ounces freshly squeezed lime juice
  • 1 ounce freshly squeezed grapefruit juice
  • 2 1/2 ounces fresh watermelon juice*

  • salt for rimming the glass
  • lime slices for garnish
  • grapefruit slices for garnish
  • watermelon slices for garnish

  1. Moisten the edge of your glass with a lime wedge and rim in salt. Fill the glass with crushed ice. Add a few ice cubes to a cocktail shaker and add the tequila, Grand Marnier, lime juice, grapefruit juice, watermelon juice, and simple syrup. Shake for 20-30 seconds and pour in the glass. Garnish with a lime slice, grapefruit slice, and a watermelon slice. Enjoy!

Recipe Notes

*For the simple syrup, bring 1 cup water to a boil in a medium saucepan. Once boiling, add 1 cup sugar and stir for 30 seconds or until dissolved. Remove from heat and let cool completely.
*To make watermelon juice, cut up a watermelon into cubes (discard the rind), add to a blender, and blend until smooth. Strain through a fine mesh strainer and voila! I used one baby watermelon which was about 7 cups of watermelon, and it made a ton of extra juice.
*Makes a lot of extra simple syrup. Will keep in the fridge for up to 2 weeks!
*If you want to make these pitcher-style for a crowd, I'd measure all of the margarita ingredients out for how many people you want to make them for, add everything to a pitcher, and chill the mixture in the fridge. When you're ready to serve, add the crushed ice, and serve!
