Ingredients (per 1 serving):
2 ounces fine tequila (I like Casa Noble, Herradura Reposado, Tequila 7 Leguas, & Azul, but anything will do)
½ ounce triple sec
1.5 ounces lime juice
2 ounces agave syrup or simple syrup
1 cup seedless watermelon
4 large basil leaves (when available use basil flowers for added flavor)
Place basil, lime, watermelon, and simple syrup (or agave) in cocktail shaker (you can add more or less syrup to taste)
Muddle all ingredients in cocktail shaker together
Fill shaker with ice
Add tequila and triple sec
Shake it up!
Rim margarita/cocktail glass with Tajin and fill with ice
Strain cocktail over iced glass and add garnishments if you like
Enjoy solo or with a couple of tacos (friends will work too)!
