It's a long running conspiracy by Big Salt to keep you buying their product much more than you need to.

What would make salt optimum versus sub-optimum?

Only 2 things I can think of and to me, they are minor at best.

Iodized salt can break down when iodine dissipates over about a 5 year period or if the salt is not stored in a dry place in an airtight container and moisture can get to it. And all that really does is make it clump up a bit as anyone who lives in S.E. La. and buys Morton Salt in those cardboard containers is fully aware of.

Put the cardboard container in most kitchen cabinets, don't use it for a while and when you do, it is usually about as solid as a brick until you mix it up and break up the clumps.

I'm not throwing out salt no more than I'd throw out honey, which has an indefinite use by date--------again, if stored properly.

So how do you store honey so it doesn't crystalize? I throw out so much honey because I can't use it fast enough, then it turns to rock candy. I try to microwave or soak the jar in hot water. Poor results.
