Salt is a basic food staple and required to maintain a healthy body. Consumed in excess, however, salt can cause high blood pressure and dehydration and lead to a variety of health problems. Most processed foods contain above average levels of salt.
Gourmet Salt
Recipes usually call for simple table salt, but many cooks prefer to use the larger crystals of kosher salt for cooking. Other more expensive "boutique" salts come from parts of the world like Hawaii and France and are sold in luxury cooking stores. Pink salt, smoked salt, fleur de sel, and black salt are some of the salts that can be found as part of this trend.
