Last week I was experimenting with new cocktail ideas and stumbled onto this combination of rosemary + watermelon in addition to the traditional margarita ingredients of tequila and lime. It might sound bizarre, but this is one of the best flavor combos I’ve ever tasted in a cocktail recipe.

First, the rosemary. It’s no secret that herbs work extremely well in drinks. The alcohol brings out the fragrant oils in the herbs, and this is no exception – the rosemary in the tequila creates the most incredible aroma that pairs perfectly with the sour lime and fruity watermelon flavors. It’s one of those things you’ve got to taste to understand.

It’s also extremely easy to make! Just 4 ingredients, and would be great to multiply the recipe x5 for a big summer party.

Makes 2 drinks


  • 4 oz tequila
  • 2 oz lime juice
  • 3-4 large sprigs rosemary
  • 1/3 cup diced watermelon (+slivers for garnish)
  • Salt, for garnish

Pro tip: One of the keys to this recipe is using really sweet and flavorful watermelon, since this cocktail has no added sugar. If your watermelon is a little on the bland side, feel free to add a drop of agave or triple-sec, the traditional way to sweeten a margarita.

Step One

In a blender combine the tequila, lime juice, watermelon, and the leaves from 2 sprigs of rosemary (pull the leaves off the stems and discard the stems). Blend until the watermelon is smoothly pureed and the rosemary is broken into small bits. For best results, let this sit for 5-10 minutes so that the rosemary can infuse into the tequila.

Step Two

Prepare the serving glasses by wetting the rims and dipping them into salt, then add an ice cube to each glass along with a sprig of rosemary and a slice of watermelon.

Step Three

To serve, use a regular kitchen strainer to strain the liquid into a pitcher or directly into the glasses, straining out and discarding the bits of watermelon and rosemary.
