Are Luxardo Cherries Worth the Money?
by Tommy Werner and Joe Sevier @ Epicurious
Out of the jar or tin, Luxardo cherries are nothing like the candy-apple red lumps bartenders plunk into kiddie cocktails. They are a touch of class, the dark, perfect capper to a stiff drink. Their red is so deep, it's almost black; their syrup thicker than molasses on a chilly day. The taste is nutty like Amaretto and fruit-forward, without the sticky and acrid taste that waxy imitation maraschinos have.
Where the American maraschino cherry feels kitschy and nostalgic, the Italian Luxardo cherry exudes elegance. These make you feel special. Luxe, even. Spoon one—or a few—cherries into an icy Manhattan, the sweet cherries play off the drink's red vermouth and reduce the bite of the bourbon. Like sours? The Luxardo cherry is an outrageously good complement to sour mix. And don't forget about that syrup—stir a spoonful of it into a whisky, pisco, or other sour, and look out.
