At a glance

When to choose Halen Môn Sea Salt

Reach for Halen Môn when you want the softer, rounder British flake with provenance to match. It is the Welsh standard, pure sea salt hand-harvested from the Menai Strait off Anglesey and PDO-protected since 2014, so the name guarantees the origin. The flakes are lighter and softer than Maldon, giving a gentle crunch that melts into a clean, rounded brine with a soft mineral note and a touch of sweetness, never sharp. That rounded gentleness suits Welsh lamb and a Sunday roast especially well, along with roast potatoes, fresh bread and butter, seared fish, salads and dark chocolate, crushed over the plate at the table just before serving. Keep it off long braises, where the crunch is lost, and out of boiling and brining water, where a cheaper coarse salt does the job. Against the Cornish, the difference is one of character more than quality: Halen Môn is the softer, rounder, gentler flake, while the Cornish is crisper and brisker, so the choice often comes down to the plate and to whether you value the PDO badge. At about £6 a tub it costs a little more than the Cornish, but that buys certified Welsh provenance, proper documentation for the price of a sandwich, and it keeps for years in an airtight tub. For a roast where you want a soft, clean crunch and a salt with a real name behind it, Halen Môn is the pick; for brisker, cheaper everyday finishing, the Cornish is right there alongside it.

When to choose Cornish Sea Salt

Reach for Cornish sea salt when you want a crisp, bright British finishing flake at the keenest price. Harvested off the Lizard Peninsula in Cornwall, it is a small, crisp Atlantic flake, finer than Maldon, with a brisk, bright brine and a clean mineral note. Crushed over the plate raw, just before serving, it gives a fine fresh crunch that melts quickly and clean, made for fish and chips, seared fish and seafood, a Sunday roast and roast potatoes, salads, fresh bread and butter, and chips and fries. Keep it off long braises and out of boiling water and brines, where a cheap coarse salt does the same job. Against Halen Môn, the Cornish is the crisper, brisker flake where the Welsh is softer and rounder, and it has no PDO badge, but it is cheaper, around £3 to £4 a tub versus about £6, which makes it the easy everyday choice when you are finishing in volume. On fish and chips especially, that brisk Atlantic edge feels right at home. Neither is better in absolute terms; they are two good British flakes tuned a little differently, and a kitchen could happily keep just one. Choose Cornish when value and a crisper crunch matter more than the appellation, and Halen Môn when you want the softer flake and the certified Welsh provenance. It keeps for years in an airtight tub, so a tub of either covers a long run of dinners. For most everyday British plates, the Cornish is the thrifty, dependable default.

Frequently asked questions

Is Halen Môn worth more than Cornish sea salt?

It depends on what you value. Halen Môn at about £6 a tub buys a softer, rounder flake and PDO-certified Welsh provenance since 2014. Cornish at £3 to £4 gives a crisper, brisker crunch for less. Both finish a plate well, so the premium is mostly about provenance and flake style.

What's the difference in flavor and texture?

Halen Môn is the softer, rounder, gentler flake with a clean brine and a touch of sweetness. Cornish is crisper and brisker with a bright Atlantic edge. The differences are subtle; both are clean, additive-free British sea salts suited to finishing the plate.

Which suits a Sunday roast or Welsh lamb?

Both work, but Halen Môn's soft, rounded crunch is a natural match for Welsh lamb and a Sunday roast. Cornish is equally at home on a roast and shines on fish and chips. If provenance matters, the Welsh PDO salt edges it for the roast.

Can I cook or brine with these?

No, both are finishing salts. Long braising loses the crunch and brining wastes the fine flake. Use a cheap coarse salt for boiling water and brines, and crush either one over the plate at the table for the final crunch.
