Salty Dog
1.5 oz vodka or gin
3 oz grapefruit juice
Garnish: salt rim
Wet the rim of a highball glass and dip it in coarse salt.
Fill the highball glass with ice, then add the vodka (or gin) and grapefruit juice and stir gently to combine. Alternately, you can add a pinch of the salt directly into the drink.
