Oskoid

From Memory Alpha, the free Star Trek reference.

Oskoid is a leaf-like Betazoid food, dark yellow with purple veins that contain sap said to keep one warm. It is a favorite food of Lwaxana Troi. (TNG: "Ménage à Troi")

Lwaxana Troi replicated some oskoids when she was aboard the USS Enterprise-D in late 2367. Oskoids are considered as a Betazoid delicacy. (TNG: "Half a Life")
