Orange bitters are a kind of bitters, a cocktail flavoring obtained from such ingredients as the peels of Seville oranges, caraway seed, cardamom, coriander, anise, and burnt sugar in an alcohol base. Orange bitters, which are not to be confused with the official Angostura aromatic bitters, are currently enjoying a resurgence among cocktail lovers.
