The champagne of sea salt. Harvested only on certain days in summer at the ideal junction of sunlight and humidity when a white bloom—le fleur or “the flower” of salt—appears on the water in French salt marshes (for use in traditional salt grinders). 4¼-oz. Sel Marin - Sharper and bolder in flavor than Fleur de Sel, it is gathered in salt marshes of the Atlantic ocean in Brittany, France. Slowly crystallized by the wind and sun, Sel Marin is naturally rich in magnesium, calcium, potassium and trace elements; never washed or refined (for use in traditional salt grinders). 35-oz.
