Elvish waybread, a sustaining food prepared by the Elves for long journeys. Thin cakes wrapped in mallorn leaves, lembas remains fresh for many days and a small portion satisfies a traveller for a full day's march. It is food of the Eldar, and its making is a closely guarded tradition. Frodo and Sam rely on lembas during their gruelling journey through Mordor, where it sustains them when all other food is gone. Gollum cannot bear to eat it.
