225 ml. tequila
4 tablespoons Triple sec or Cointreau
2 large limes
8 ice cubes
Squeeze the juice from the limes, reserving the lime halves. Moisten the rims of four cocktail glasses by rubbing with the reserved squeezed lime halves. Put the salt on a saucer and dip the rim of the glasses in it.(Do not attempt to do this with water as it dissolves the salt) Place the lime juice in a blender, add the tequila, the Triple Sec or Cointreau and the ice cubes, and blend at high speed for 30 seconds. Pour into the chilled glasses. If you wish to make this drink weaker, add more ice and less of the mixture to each glass.
