Which sea salt for crispy roast potatoes?
Season : all-year · Occasion : sunday roast, christmas, weekend
Cornish Sea Salt. Toss the small, crisp Atlantic flakes over the potatoes the moment they leave the oven, while the crust is hot and rough, so the brine grips the ragged edges. The fine flake melts cleanly into the crunch. Don't salt them after they've cooled, when the crisp surface has set and the salt just rolls off.
In detail
The best sea salt for crispy roast potatoes is Cornish Sea Salt, the small, crisp Atlantic flake harvested off the Lizard Peninsula in Cornwall. Its brisk, bright brine and fine flake catch on a rough roast crust where a finer table salt would read flat. The move that matters is timing: toss the salt over the potatoes the instant they leave the oven, while the surface is hot and craggy, so the brine grips the edges and half-melts in. Salt them after they cool and the set crust just sheds the crystals onto the tray. Season the par-boil water with cheap coarse salt to flavour through, and save the Cornish flake strictly for the finish. It's a sound everyday flake at around £3 to £4 a tub, the British workhorse for a Sunday roast. Maldon gives a bolder, more visible crunch if you prefer statement flakes.
Our recommendation
Salt · Flaky sea salt
Cornish Sea Salt
Lizard Peninsula, Cornwall, England
bright Atlantic brine · clean mineral · fresh sea note
Crispy roast potatoes need salt that catches on a rough, hot crust, and Cornish Sea Salt's small, crisp Atlantic flakes do it cleanly, with a brisk, bright brine and no bitterness. Tossed on straight from the oven, the fine flake half-melts into the craggy edges and gives an even, snappy season without the larger-pyramid clumps of Maldon. It's a sound everyday flake at around £3 to £4 a tub, the British workhorse for a Sunday roast.

The catch
Don't salt your roast potatoes once they've cooled on the side. The crisp crust sets within a couple of minutes out of the oven, and after that the flakes have nothing to bite into, so they roll straight off onto the tray. That hot, rough, just-out surface is exactly what grips salt. Toss the Cornish on the second the tin comes out, or you've seasoned the roasting tray and left the spuds bare.
Chef's note
Salt in two stages. Heavily salt the par-boil water with cheap coarse salt so the potato is seasoned through, then roast in hot fat until craggy. The instant they're out, scatter Cornish flake over the tray and toss so every potato passes the salt while the crust is still hot and grabbing. A final pinch as they hit the serving dish keeps the bright top note alive.
Tasting note
bright Atlantic brine · clean mineral · fine snap · around £3 to £4 a tub, the cheapest flaky salt here and a proper everyday workhorse. Worth it.

Alternatives to explore
-
Salt · Flaky sea salt
Maldon Sea Salt
Maldon, Essex, Blackwater estuary, England
Intensity 7/10
Maldon's larger pyramids give a bolder, more occasional crunch on the potato. The pick if you want statement flakes you can see, though it scatters less evenly than Cornish.
-
Salt · Flaky sea salt
Halen Môn Sea Salt
Anglesey, Menai Strait, Wales (PDO)
Intensity 6/10
Halen Môn is softer and PDO-protected, with a rounder brine. The provenance pick for a Welsh Sunday table, a touch gentler than Cornish's brisk Atlantic snap.

Frequently asked questions
- When do you salt roast potatoes for the crispiest result?
- The moment they come out of the oven, while the crust is hot and rough. The brine grips the craggy surface and half-melts in. Salt them after they cool and the set crust just sheds the crystals onto the tray.
- Should you salt roast potatoes before or after roasting?
- Salt the par-boil water with cheap coarse salt to season through, then finish with flaky Cornish straight from the oven for the crunch and the bright top note. Salting the raw potatoes with flake before roasting wastes the texture.
- Is flaky salt better than table salt on roast potatoes?
- As a finish, yes. Flaky Cornish gives bright bursts of brine and a snap that fine table salt's even cure can't. Use cheap salt in the water, and save the flake for the toss off the heat.
