The origin of the salt and lime with Tequila goes back when it was first being distilled, at that time the alcohol content was very, very high and in order to lessen the burning sensation, a pinch of salt was placed on the tongue and the shot of Tequila taken followed by the limon (lime) to sooth the sting of the alcohol and salt.
Today the Tequila industry has matured and there are Tequilas that are good and smooth as a Courvoisier or a Remy Matran, drinking these Tequilas with a pinch of salt and limon would be as bad as MEXICOWANDER stated, not to nice.
Drink yor Tequila any way that you prefer and enjoy, as long as you drink the Tequila!
