Upgraded cocktails don't have to be complicated to be complex. Like this infinitely drinkable blackberry basil margarita. It's made with easy to find ingredients and in rimmed in jade-hued basil salt.
In the bowl of a food processor, pulse salt and basil until combined. Spread evenly on a baking sheet and let dry at room temperature or a very low heated oven. Store in an airtight container up to 4 months.
Blackberry Basil Margarita
For the salt rim, pour some salt onto a small plate. Run the flesh side of the lime along the rim of a double rocks glass then carefully roll the rim through the salt to coat. Alternatively, coat one side of the glass.
In a cocktail shaker, muddle the blackberries and basil. Add the tequila, agave, Cointreau (or triple sec), and lime juice and shake with a few pieces of ice until well chilled. Strain into the rimmed double rocks glass and top with more ice.
Garnish with the lime wedge and blackberry.
Notes
Up to 4 months ahead: Make and dry the basil salt. Store in an airtight container.
