Border Margarita

Gently dampen the rim of a margarita glass with the lime slice. Dip the rim in a saucer of salt to coat.

In a blender or cocktail shaker, combine the tequila, orange liqueur, lime juice and a handful of ice cubes. Blend until smooth, or shake until chilled. Pour the margarita into the prepared glass, adding fresh ice if the margarita was shaken. Slip the lime slice on the rim of the glass and serve.
