Mint Simple Syrup

  1. To a medium saucepan, add in 1 cup of sugar, 1 cup of water, and 5-10 mint leaves.
  2. Place on the stove over medium heat and bring up to a low boil.
  3. Once at a low boil, turn down to medium-low heat and cook for 10 minutes. Stir to dissolve the sugar completely.
  4. Once finished, remove the mint leaves and store in a mason jar in the fridge until needed.


  1. Freeze your watermelon. Cut a fresh watermelon into bite-size chunks. Spread out on a baking sheet lined with parchment paper and place in the freezer for about an hour or until the watermelon is completely frozen. Store in a freezer-safe bag until ready to use.
  2. To a large blender add frozen watermelon chunks, tequila, lime juice, mint leaves, mint simple syrup, lime sparkling water, and ice.
  3. Turn blender on high for 60 seconds to thoroughly blend everything together and make a slushy marg consistency.
  4. Salt the rim of your glass. To a shallow bowl or plate add margarita salt (affiliate link) and the zest of 1/2 lime. Using the other half of the lime, rim the glass with lime juice, then place it on top of the salt and lime zest. Turn around on all sides making sure to coat the rim entirely.
  5. Pour your frozen margarita into your cup. Top with a spring of mint and a straw and enjoy!
