Also referred to as “Common Rue” or the “Herb-of-grace,” Rue Oil is derived from the Ruta graveolens herb which is wild-grown throughout the Mediterranean. Originally cultivated as a medicinal herb by Ancient Romans, the plant has since spread to many other regions of Europe, Africa, and the Middle East. The aroma of rue oil is fatty, herbaceous, and dairy-like, with a peculiar citrus note reminiscent of fresh oranges. These fatty nuances are very useful in dairy flavors, particularly those that incorporate coconut and bleu cheese. For pineapple and other tropical flavorings, rue oil’s fruity nuances also find widespread application.
