This recipe is sponsored by Cointreau. We take advantage of the end-of-summer abundance of cucumbers and fresh mint and update The Original Margarita, one of the most popular classic cocktails in the country. The recipe has been around for over 70 years and is still made with just three simple ingredients: Cointreau, tequila and lime. In this version, we start by muddling the cucumber and mint until both are fragrant and the mint has released its natural oils. Cointreau elevates this cocktail with its highly aromatic yet balanced flavor profile. Once shaken with plenty of ice and served in a glass with a salt rim, it is the most refreshing cocktail you will have this season.
Rub the rim of a rocks glass with 1 lime wedge, then dip the rim in coarse salt.
Muddle the mint and cucumber in a cocktail shaker with a muddler or the handle of a wooden spoon until the cucumber is broken up and the mint is bruised, 5 to 6 times. Add the Cointreau, tequila and lime juice. Fill the shaker three-quarters of the way with ice and shake well. Pour into the prepared glass and garnish with the remaining lime wedge.
