table salt

Table salt is sodium chloride (NaCl), a mineral compound extracted from seawater through evaporation or mined from underground salt deposits formed from ancient marine environments. The crystalline substance is refined, processed, and often treated with anti-caking agents such as sodium aluminosilicate to improve flowability and prevent clumping. Chemically pure at approximately 99.7% NaCl, table salt differs from sea salt and kosher salt primarily in crystal size, density, and processing methods. Standard table salt has fine, uniform crystals that pack densely, resulting in approximately 280 mg of sodium per teaspoon, compared to roughly 200 mg for the same volume of kosher salt.

Table salt is the primary seasoning agent across all culinary traditions, used to enhance flavor perception, preserve foods, and balance sweet and acidic elements. It is essential in cooking and baking, where it modulates flavor compounds and affects dough development and gluten formation. Beyond seasoning prepared dishes, table salt features in brining solutions for meat and vegetables, acts as a preservative in charcuterie and pickling, and serves as a texture modifier in bread and pastries. Its fine crystal structure and uniform density make it ideal for precise measurement in recipes, particularly in baking where ingredient ratios are critical.
