Muddle basil leaves into lime juice in a cocktail shaker. Add Dos Hombres Mezcal, watermelon juice and fill with ice. Shake and strain over a sugar and salt rimmed glass full of ice. Slap some Basil leaves with your palms and throw in on top of your drink for garnish for a nice aroma while drinking this delightful beverage.
To rim a glass rub a lime wedge over the rim of the glass inside and out and then dunk it into some sugar and salt. 1 part sugar and 1 part salt.
