One of my favorite uses for flavored vodka has to be Lemon Drops. As far as drinks go, they're almost foolproof. I'll even tolerate low-rent ones made with (gasp!) bottled sour mix.
While the vast majority of Lemon Drops out there are at least somewhat drinkable, a well-made one is a marvel. It almost makes you pine for the cocktail explosion of the late 1990s, back when anything Technicolor-hued in a cocktail glass was dubbed a martini.
