Salt (sodium chloride, NaCl) is a crystalline mineral compound extracted from seawater, mineral deposits, or rock formations. It is the primary source of dietary sodium and chloride ions essential for human physiology. Common culinary salts include table salt (refined and iodized), sea salt (harvested from evaporated seawater with mineral content), kosher salt (larger crystals, less dense), and specialty salts such as Himalayan pink salt and fleur de sel. Salt's flavor profile is fundamentally saline, though mineral-rich varieties impart subtle secondary notes from trace elements.

Salt is the most fundamental seasoning in global cuisine, used to enhance flavor perception, preserve foods, and control fermentation and protein extraction in cooking. It appears in nearly every savory dish across all culinary traditions, functioning not only as a direct seasoning but also as a key component in brines, curing blends, and bread doughs. Salt balances sweetness, suppresses bitterness, and amplifies aromatic compounds. In baking, it strengthens gluten networks; in preservation, it inhibits microbial growth. Different salt varieties are chosen based on crystal size, mineral content, and intended application.
