To make watermelon puree, put seedless chunks of watermelon in a blender and pulse, then push the puree through a mesh sieve to make it smoother. (Cutting a whole watermelon might make your kitchen look like a Gallagher set, so it’s O.K. to use precut watermelon from a supermarket.)

Ingredients

  • 3 parts watermelon puree
  • 1 part silver tequila
  • ½ part fresh lime juice
  • Seltzer
  • Sliced jalapeno
  • Coarse sea salt
  • Ice
  • Agave nectar (optional)

    Preparation

    1. In a large pitcher or bowl, stir together the watermelon puree, tequila and lime juice.
    2. To sweeten, adjust with agave nectar.
    3. To serve, pour into glasses over ice, top each glass with seltzer, a pinch of sea salt and slices of jalapeno.
