sea salt

Sea salt is salt obtained through the evaporation of seawater, primarily composed of sodium chloride (NaCl) along with trace minerals from the marine environment. Unlike mined rock salt, sea salt is harvested from ocean water through solar or mechanical evaporation methods, yielding crystals that retain natural mineral content such as magnesium, calcium, potassium, and iodine. The mineral composition and crystal structure vary depending on water source, evaporation method, and geographical location, producing variations in flavor, color, and texture among regional varieties (such as Maldon from England, Fleur de sel from France, or Hawaiian black salt).

Sea salt crystals are typically larger and more irregular than refined table salt, with a clean, briny flavor profile that reflects the ocean's mineral character. The crystals range in color from white to gray or pale pink, depending on mineral content and processing methods.

Sea salt is used extensively across global cuisines as both a cooking ingredient and finishing condiment. In cooking, it functions as a seasoning agent in soups, sauces, preserved foods, and grain dishes, with mineral content and larger crystals allowing more controlled salting than fine table salt. As a finishing salt, larger varieties such as Maldon or fleur de sel are applied to cooked dishes immediately before service, providing textural contrast, mineral complexity, and visual appeal without dissolving completely. Sea salt is fundamental to charcuterie, cheese-making, and fermentation processes, where its mineral composition affects flavor development and preservation. Specialty salts colored by added minerals (e.g., Hawaiian black lava salt, Celtic gray salt) are employed both functionally and aesthetically in contemporary cuisine.
