You’ll need three ingredients for this very refreshing, exemplary margarita: fresh-squeezed lime juice, a 100% agave silver, (blanco), tequila, and Cointreau. Plan on about 3 tablespoons of each per drink, meaning that 3/4 cup of each will yield about 4 margaritas.
Pour coarse (Kosher) salt into a small plate. Use a lime half to moisten the rim of your cocktail glasses then tip them into the salt to encrust the rim.
Mix equal portions of lime juice, tequila and Cointreau in a pitcher. Fill a cocktail shaker half full of ice cubes, add enough margarita mixture for a couple of drinks (a generous cup), secure the lid and shake for a full 15 seconds to chill the mixture and properly dilute it with the melting ice. Strain into the salt-rimmed glass and enjoy.
