Salt (sodium chloride, NaCl) is a crystalline mineral compound essential to human nutrition and one of the oldest and most universal seasonings in culinary practice. It occurs naturally in seawater, salt mines, and salt lakes worldwide, and is extracted through evaporation, mining, or refinement. Salt crystals range in color from white to gray to pink depending on mineral content and origin; common varieties include table salt (refined with anti-caking agents), sea salt (evaporated from seawater with retained trace minerals), kosher salt (larger crystals, minimal additives), and specialty salts such as Himalayan pink salt and fleur de sel. The flavor profile of salt is purely salty, though mineral-rich varieties may impart subtle mineral or briny notes.

Salt is the fundamental seasoning in virtually all culinary traditions, used to enhance flavor perception, preserve foods through curing and brining, and regulate fermentation in products like sauerkraut and kimchi. It is essential in baking and cooking to develop gluten structure, control yeast activity, and balance sweetness and acidity. Salt is applied at multiple stages—during cooking to season dishes, as a finishing salt on prepared foods for textural contrast, and in the form of salt brines for curing meats and vegetables. Different salt varieties are chosen for specific applications: kosher salt for its crystal size facilitates even seasoning, sea salt and fleur de sel for finishing dishes, and pickling salt for preserving.
