In a pitcher or a cocktail shaker, combine the tequila and the ice cubes and stir or shake 20 times. Place the Triple Sec in a chilled cocktail glass, swirl it around to coat the inside of the glass, and discard it. Strain the tequila into the glass. Thread the twist of lime and the strip of chile onto the cocktail skewer, perch it on the rim of the glass, and serve at once.
This recipe yields 1 martini.
