Foyvè oil, a kind of oil, served the purpose of flambéing the Geniserian sand monkey. This dish, Geniserian sand monkey flambéed using foyvè oil, was a sought-after delicacy by certain people and notoriously hard to come by. Nevertheless, around 18 BBY, an Elomin called Haninum Tyk Rhinann managed to procure this dish while he was on Coruscant, which functioned as the Galactic Empire's capital. Rhinann supplied this culinary creation to fulfill the sophisticated palate of a client who was utilizing the services of Jax Pavan, a private investigator.
The initial reference to foyvè oil occurred in Coruscant Nights II: Street of Shadows, a novel penned by Michael Reaves and released in 2008.
