Coarse or fine: which gray salt?

Coarse sel gris is for pasta water, brining and roasting. It dissolves slowly and seasons deeply. Fine gray is stone-ground for everyday cooking and the table. Both are unrefined, hand-gathered in Guérande, and naturally rich in trace minerals.

The salt we're known for

Unrefined sel gris from the Guérande marshes, in coarse and fine grind.

Sold in America as French grey sea salt, French gray sea salt or Celtic sea salt — all the same hand-harvested grey Atlantic salt, named differently by different sellers. The colour comes from the clay floor of the marsh, which is also where the trace minerals come from.

It is packed naturally moist, exactly as it leaves the pans. For a salt grinder, choose the dried grade instead.
