Best all-purpose sea salt for a seafood boil?
Season : summer · Occasion : cookout, party, celebration
Noirmoutier sea salt, by the handful. A boil needs heavily seasoned water, so reach for a cheap clean sea salt you can use generously, not a precious finishing flake. Its frank Atlantic salinity and faint iodine season shrimp and crab from the inside as they cook. Salt the water hard, like the sea.
In detail
The best all-purpose sea salt for a seafood boil is a cheap, clean one you can use generously, such as Noirmoutier. A boil works by seasoning a large pot of water close to seawater strength, roughly 35 grams per liter, so the shrimp, crab, corn and potatoes take on seasoning from the inside as they cook. That makes the precious texture and provenance of a finishing flake beside the point: it would dissolve invisibly and you would be pouring money down the drain. What you want instead is a frank, bitterness-free salinity at a price low enough to salt the pot hard without flinching. Noirmoutier sea salt, hand-raked from the tidal marshes off the Vendée coast, fits exactly, carrying a clean Atlantic iodine that flatters shellfish, and it costs only about $5 to $8 a kilo. Salt the water like the sea, and skip the boutique salt here.
Our recommendation
Salt · Sea salt
Noirmoutier Sea Salt
Noirmoutier Island, Vendée, Atlantic coast, France
frank salinity · clean brine · wet mineral
A seafood boil is the wrong place for an expensive salt, because you season the water by the handful and most of it goes down the drain. Noirmoutier is exactly right: a clean, frank, all-purpose sea salt with no bitterness, at roughly $5 to $8 a kilo, so you can salt the pot hard without flinching. Its Atlantic iodine also flatters shrimp, crab and corn as they cook through.

The catch
The catch: a seafood boil is the worst place for an expensive salt. You season the pot by the handful, close to seawater strength, and most of that salt goes down the drain when you tip the pot out. Spend finishing-salt money here and you are pouring it away. Reach instead for a clean, cheap all-purpose sea salt you can use with a heavy hand. Noirmoutier salts the water hard for a few dollars a kilo, and the shellfish season from inside as they cook.
Chef's note
Salt the water until it tastes like the sea, roughly 35 grams per liter, before anything goes in, and add aromatics, not more salt, for flavor: bay, lemon halves, a split head of garlic, your spice blend. Stage the pot by cook time, the potatoes and corn first, then sausage, then the shrimp and crab for the last few minutes so nothing turns rubbery. Drain and tip onto the table; a light finishing sprinkle is optional, but the water did the work.

Sel Gris de Guérande

Sel gris does the same honest job in a boil at a similar price, with a touch more clay-mineral depth. Either French sea salt seasons the water well; buy whichever is cheaper by the kilo.
Frequently asked questions
- How salty should seafood boil water be?
- Salt it hard, close to seawater, which is roughly 35 grams per liter. The seafood seasons from the water as it cooks, so under-salting the pot leaves bland shrimp and crab that no amount of finishing salt can fully fix.
- What kind of salt is best for a seafood boil?
- A cheap, clean all-purpose sea salt you can use generously, like Noirmoutier. You are seasoning a large pot of water by the handful, so the texture and provenance of a finishing salt are wasted; what matters is clean salinity at a low price.
- Should I salt the seafood or just the water?
- Mainly the water. A well-salted boil seasons shrimp, crab and corn from the inside as they cook. A light finishing sprinkle at the table is fine, but the heavy lifting is done by the salinity of the pot.
