Salt is a crystalline mineral compound (sodium chloride, NaCl) that occurs naturally in seawater, salt mines, and salt lakes worldwide. It has been harvested and refined for thousands of years and is essential to human nutrition and food preservation. Salt crystals are colorless to white, with a distinctive saline taste that enhances and balances flavors in cuisine. The primary sources are sea salt (evaporated from seawater) and rock salt (mined from underground deposits), with variations in mineral content and crystal size depending on origin and processing methods.

Salt is the most fundamental seasoning in culinary practice, used to enhance flavors, balance sweetness and acidity, and draw out moisture in meats and vegetables. It is essential in baking for gluten development, in curing and preservation of meats and fish, and in brining for moisture retention. Beyond direct seasoning, salt appears in condiments, stocks, sauces, and fermented foods. Different varieties—kosher salt, sea salt, and specialty salts—are employed based on crystal size, mineral content, and intended application, from finishing dishes to seasoning cooking water.
