Grand Marnier flavoring is an ORANGE-flavored liqueur made from a blend of cognac and bitter ORANGE. It is produced by the House of Marnier-Lapostolle, which was founded in 1827 by Jean-Baptiste Lapostolle and his son-in-law, Louis-Alexandre Marnier. The ORANGE flavor comes from the distillation of sweet and bitter ORANGE peels. Grand Marnier flavoring is used in many recipes, including desserts, cocktails, and sauces.
