For the jalapeño simple syrup:

  • 1/2 cup granulated sugar
  • 1/2 cup water
  • 1 jalapeno , diced (seeds removed if you don't like things super spicy)
  • 5 cups diced watermelon
  • Juice from 1 lime
  • 2 cups soda water


  1. For the jalapeño simple syrup: In a small saucepan over medium heat, add sugar and water. Let cook until sugar has dissolved and then remove from heat. Add in jalapeño and let steep for at least one hour. Strain out jalapeño and transfer syrup to a sealable jar. Stick in fridge until ready to use.
  2. Working in batches, puree the watermelon in a blender and then strain through a fine mesh strainer. Stir in lime juice. Transfer to a pitcher and add soda water and ice. Add in 1/4 cup simple syrup and taste. Add more simple syrup if desired.
