The recipe includes a mix of grapefruit, orange and lime juices with tequila, a pinch of salt and a Tajin rim for a little kick. The soda used in this cocktail is Jarritos, another reference to the Mexican clay drinking vessel. Tequila is the backbone of this recipe, so use a good-quality blanco or reposado.
