Sel Gris

From the French Atlantic

Sel Gris is harvested from salt marshes along the Atlantic coast of France, primarily in the Guérande peninsula in southern Brittany. The process begins when high tides push seawater through a series of shallow clay-lined channels and pools. Over weeks of sun and wind exposure, the water slowly evaporates and salt crystals settle to the bottom, absorbing minerals from the clay lining. Salt workers called paludiers use wooden rakes to gather the grey crystals. This artisanal process produces salt that retains the mineral complexity of the sea and the earth.

Cooking with Grey Salt

Sel Gris is a versatile kitchen salt that works both during and after cooking. Its coarse, moist crystals make it ideal for rubbing onto roasts, seasoning thick steaks before grilling, and adding to stew pots. French chefs use it as their everyday cooking salt. For a classic preparation, pack a whole fish in a thick layer of Sel Gris mixed with egg whites and bake until the crust hardens-this is the traditional French 'poisson en croûte de sel.' The salt crust seals in moisture and seasons the fish perfectly.
