Signs kosher salt has gone bad
- Hard caking — the crystals fuse into one solid lump.
- Damp clumps that won't pour or measure cleanly.
- An off or musty smell from odours it absorbed.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store kosher salt
Kosher salt is coarse and made without anti-caking agents, so it loves to set into a solid block once steam from the stove reaches it. Keep it dry and tightly sealed in a cupboard away from the stove, and it stays good practically forever.
