coarse salt

Coarse salt refers to larger crystalline salt particles, typically produced through evaporation of seawater or harvested from rock salt deposits. The term encompasses various types including sea salt, kosher salt, and finishing salts, which share a common characteristic: granules significantly larger than table salt (typically 2–4 mm). These crystals remain distinct and visible in finished dishes, dissolving more slowly than fine salt due to their reduced surface area. Coarse salt varieties vary by origin—sea salt contains trace minerals from ocean water, while rock salt is mined from ancient mineral deposits. The flavor profile is essentially pure sodium chloride, though sea salts may carry subtle briny or mineral notes depending on their source waters.

Coarse salt serves multiple functions in professional and home cooking. It is used as a finishing salt, sprinkled over dishes immediately before serving to provide textural contrast and intense bursts of salinity. In baking, it functions as a base for salt crusts on fish and vegetables, creating a moisture-trapping barrier during roasting. Coarse salt is preferred for brining, dry-curing, and curing preparations due to its slow dissolution rate and ability to extract moisture evenly. It is also standard for rimming cocktail glasses and used in salt mills for tableside grinding. Its larger crystals make it easier to pinch and gauge quantity than fine table salt, making it a staple for seasoning during cooking rather than for chemical precision.
