I've been on a crazed hunt for the perfect Halloween  cocktail. I envisioned a black martini, but the only recipes I could find involved chocolate-flavored vodka. Don't get me wrong: There is a time and a place for chocolate vodka, but Halloween  is not that time or place.
When I saw this recipe for a Black Widow, I assumed it involved chocolate, but —surprise! — it's actually dark grape juice that gives this drink a glorious hue. To get the devilishly delicious recipe I'll be making on All Hallow's Eve,
From 42 Below
