Signs sea salt has gone bad
- Flakes crushed down to fine, characterless dust.
- Hard caking or damp clumps from humidity.
- Faded or vanished smoke aroma in smoked salt.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store sea salt
Sea salt keeps forever when dry, but its delicate flakes crush to plain dust if you pack them down, and smoked sea salt loses its smoky aroma fairly quickly. Store it sealed in a cool, dry cupboard, away from steam.
