Margarita Salt is a sea salt with coarse grains which is usually used for coating the rim of a Margarita glass. The coarse Margarita salt consists of large crystals and can also be coloured due to the impurities of the water from which it is derived. The crunch of the Margarita salt on the glass provides a great feel in the mouth and it complements the flavour of the margarita drink. Margarita is a cocktail in which tequila and lemon juice are mixed and the glass is coated with sugar or margarita salt and it is served with ice or without ice depending on oneâ€™s preference. Apart from this margarita salt is also used for cooking in many margarita salt recipes.
