Is flaky sea salt the same as coarse sea salt?

By The Salt AlmanacUpdated November 8, 20261 source cited

Short answer

No. Both are sea salt, but the crystals form differently. Flaky salt, like Maldon, forms thin, hollow pyramid flakes at the surface of evaporating brine; it crushes easily and is used for finishing. Coarse sea salt has hard, chunky crystals that suit grinders, salt crusts and cooking water.

How the shapes form

Flaky salt crystallises at the surface of warm brine. Small crystals float and grow outward into hollow, stepped pyramids and thin flakes, which are then skimmed off.

Coarse salt grows as solid, cube-like or irregular chunks, often at the bottom of salt pans or from rock salt.

When to use each

FlakyFinishing steak, salads, bread and chocolate; crushed between the fingers.
CoarseGrinders, pasta water, brines, salt-crusted fish, pretzels and roasted vegetables.

Same salt, different texture

Chemically they are both mostly sodium chloride. The difference is texture and how they dissolve.
