Fleur de sel is a type of sea salt that is harvested from the surface of salt ponds, primarily in coastal regions of France. It is known for its delicate, flaky texture and light gray color, which comes from the minerals found in the seawater. This salt is often considered a finishing salt, used to enhance the flavor of dishes just before serving. The harvesting process of fleur de sel is labor-intensive, as it requires skilled workers to carefully collect the salt crystals that form on the water's surface. Due to its artisanal production and unique flavor profile, fleur de sel is often more expensive than regular table salt and is prized by chefs and food enthusiasts alike.
