I have a shaker of salt on my table, and (fingers crossed) it still tastes salty. But I'm concerned that someday it will lose its saltiness and then I wouldn't know what to do.
Is there something you can add to salt that will make it "saltier"? Are there things that are saltier than salt? Or things that taste salty for a different reason, so, eg if someone loses their salt-tasting taste-buds they could still detect something as salty?
