Steeped with herbs, citrus peels and spices, BITTERS were used as medicine back in the day -- pre-19th century! Today, they're trending at the bar. Add a few drops to cocktails to balance sweet or fruity flavors, or to give a kick to gin and tonic or sweet liquor such as bourbon or rum. The most popular type is angostura, derived from a bitter-tasting root, but other versions are made with chocolate, grapefruit or even spicy sriracha.
