– 1 teaspoon salt

Salt is a mineral compound, primarily sodium chloride (NaCl), obtained from evaporation of seawater, rock salt deposits, or brine wells. It is an odorless, colorless crystalline solid with a distinctly salty taste. The primary forms include sea salt (harvested through solar evaporation of seawater), rock salt (mined from underground deposits), and refined table salt (processed and often iodized). Sea salt crystals vary in size and mineral composition depending on origin, while table salt is uniform and finely ground, often containing anti-caking agents and iodine additives.

Salt is essential for human physiology, regulating fluid balance, nerve function, and muscle contraction. Beyond nutritional necessity, salt is the fundamental seasoning in all cuisines, enhancing flavors by suppressing bitter compounds and amplifying umami notes.

Salt is the primary seasoning in virtually all savory cooking, used to enhance natural flavors in dishes ranging from stocks and soups to grilled meats and vegetables. It is essential in baking, where it strengthens gluten development in bread doughs and controls fermentation rates. Salt serves preservative functions in curing, brining, and pickling processes. It is employed in finishing dishes for textural contrast (fleur de sel, maldon salt) and throughout cooking stages—from seasoning cooking liquids to final taste adjustments. Different salt varieties (kosher salt for its larger crystals, sea salt for mineral complexity, specialty salts for garnish) are selected based on culinary application and desired sensory impact.
