2 parts tequila
1 part Curacao Triple Sec
1 part lemon juice
salt
ice cubes
cocktail glass
Rub the rim of the cocktail glass with lemon (on the outside only) and dip the lip of the glass into salt. Now mix all ingredients with some ice cubes in a shaker and strain into the cocktail glass (the ice cubes stay in the shaker).
If possible use fresh squeezed lemon juice. There´s at least 1 oz. (= 3 cl) of juice in every lemon.
