Grand Marnier is a French liqueur created in 1880 by Louis-Alexandre Marnier-Lapostolle, who blended Cognac with the essence of bitter orange peels (Citrus aurantium, also called Seville orange).
Its flavor profile combines vibrant orange aroma and taste with underlying notes of vanilla, caramel, and the smoothness of Cognac.
In the kitchen, Grand Marnier is a classic ingredient in French desserts such as crêpes Suzette, soufflés, and chocolate desserts, and in Italian tiramisu. It pairs well with chocolate, coffee, nuts, and spices like cinnamon and nutmeg. In cocktails it is a key ingredient in the Margarita, Sidecar, and Cosmopolitan, and can be enjoyed on its own as a digestif.
