You will need a cocktail shaker for this one!
Place Tequila, Triple Sec, lime juice and ice into a cocktail shaker. Give it a good shake to mix and chill the cocktail. Pour into a salt rimmed glass and garnish with a lime wedge.
To salt the rim of the glass: place some sea salt on a plate. Rub a lime wedge across the rim of the glass. Turn the glass upside down and dip it on the salt.
