Here's What You'll Need
blackberries, basil, simple syrup, tequila blanco, lime juice, cointreau, salt
Place blackberries in a cocktail shaker, add basil leaves and simple syrup. Use a muddler to crush the blackberries and bruise the basil.
Fill the shaker with ice, then add tequila, fresh lime juice, and Cointreau. Secure lid, then shake for 10-12 seconds to aerate the drink.
Run a lime wedge along the rim of a glass, then dip upside down into a bowl of salt. Place ice in glass. Strain into glass and serve with additional blackberries, basil, and/or lime for garnish.
