Pour coarse (Kosher) salt into a small plate. Use a lime half to
moisten the rim of your cocktail glasses (I typically use martini
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
