<p>Fleur de sel ("Flower of salt" in French) is a hand-harvested sea salt collected by workers who scrape only the top layer of salt before it sinks to the bottom of large salt pans. Traditional French fleur de sel is collected off the coast of Brittany most notably in the town of Guérande (Fleur de Sel de Guérande being the most revered), but also in Noirmoutier, Ile de Ré and Camargue. It is an artisanal food product. Due to its relative scarcity, fleur de sel is one of the more expensive salts.
Fleur de sel is often slightly grey due to the sand collected in the process of harvesting the salt from the pans. On occasion, the presence of Dunaliella salina (a type of pink microalgae commonly found in salt marshes) can give it a light pink tint. It is usually sold in sealed jars.
Fleurs de sel contain more mineral complexity than table salt. The following is a chemical analysis of Flos Salis, a Portuguese fleur de sel:
Parallels to authentic fleur de sel, sourced from other territories, include:
Sel gris is another type of salt that is harvested from the same salt pans as fleur de sel.
