Tequila - The best quality you can find
	Orange liqueur, such as Triple Sec or Cointreau
	Lime juice, preferably fresh-squeezed.
	Crushed ice

In a blender, mix two parts Tequila, one part Triple Sec, and one part lime juice. Add an equal amount of crushed ice and blend until slushy...or serve on the rocks.  Pre-chilling the Tequila and Triple Sec in the freezer is optional and recommended in hot weather.
Serve in a margarita glass with a salted rim, garnish with a slice of lime. To salt the rim, pour kosher salt onto a plate in a circle about the size of the rim of the glass about 1/4 inch thick. Moisten the rim of the glass with a lime, and place the edge of the glass into the salt. Let the glass stand to dry for about a minute, then carefully pour the blended drink into the center of the glass.
