The Science of the Salty Dog

The other day when I was behind the stick, one of my guests ordered a drink that I haven't made in a while, a Salty Dog. It's one of those basic drinks that you learn early on as a bartender, then almost never make because hardly anybody orders them anymore.

It's a variation on the Greyhound, a highball consisting of nothing more than vodka and grapefruit juice. The ingredient that turns a Greyhound into a Salty Dog is easy enough to figure out: salt. Specifically, it gets salt on the rim of the glass, just like on a Margarita.
