The term designates a seasoned salt mixture intended to enhance the flavor of certain beverages, particularly light lagers and Mexican-style beers. It typically consists of salt, and often includes flavorings such as lime, chili powder, and other spices. The application generally involves moistening the rim of a glass and then dipping it into the seasoning blend, allowing the crystals to adhere before pouring the beverage.
This product’s appeal lies in its ability to add a contrasting salty and often tangy or spicy element to the drinking experience. It can complement the inherent flavors of the beer, creating a more complex and refreshing profile. Its origins are somewhat diffuse, but it is closely associated with cultures where beer is commonly served with lime and salt, providing a convenient method for achieving that specific taste.
