what is fleur de sel and where do you purchase

Many good grocery stores also carry it in their bulk bins section.

Fleur de Sel, translated means flower of the sea. It is basically good sea salt, usually it is course grained. It is not meant to be used when a recipe asks for salt (ie just use plain kosher salt or table salt if thats what you usually use.) It is used more as a finishing salt, ie sprinkled on caramel/chocolate or on top of plated steaks etc.You can find it in many gourmet grocer's or places like williams sonoma etc. It is also easily found online.
