I confess to using that Malden sea salt nowadays, which does indeed go for Dewalt-style prices when compared to standard Saxo. I think it's nicer, though I've not done double-blind tasting. (But if I'm adding salt to a dish, I'll pour out the salt onto my hand until it looks like the right amount, then cast it into the pan -- and afterwards I find I lick any stray crystals off my hand, which I'd never have bothered doing with Saxo.) I kid myself that sea salt, with a wider range of halides, is stronger (more saltiness per gram) than rock salt and so healthier because you use less -- but it could be all in my head.
