Reminds me of this insane video (tasting chloride salts of Lithium, Sodium, Potassium, Rubidium, and Caesium): [VIDEO] FWIW no one has ever noticed my use of 50% NaCl/50% KCl mixture ("Lite Salt") in place of NaCl. I think when you actually put that mixture on food it would be almost impossible to notice the difference.
