Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts. Salt is indispensable for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation. Salt comes in a range of shapes, sizes and colors. These different qualities of salt are determined by the area of the world where they are mined and the way in which they are harvested or processed. Depending on the type of salt there may be additional minerals in the makeup of the crystals that are highly sought after. Salts can also be smoked over different types of wood giving them a smoky flavor. These are a delicious addition to any food you would like to taste like it came straight off the grill.
