A green vegetable with fleshy roots from Acamar III, prepared for William Riker by the cook Yuta as parthas à la Yuta in The Vengeance Factor.
Parthas is an Acamarian vegetable seen in The Next Generation episode The Vengeance Factor, set in 2366.
Yuta, the quiet cook and food taster of Sovereign Marouk of Acamar III, travels on the Enterprise-D while Picard tries to reconcile the Acamarians with the outcast Gatherers. Riker, a keen cook himself, is drawn to her and finds her preparing a dish she calls parthas à la Yuta. She explains that parthas is a green vegetable with fleshy roots, and he tastes it with approval.
The gentle scene hides a grim truth. Yuta is the last of the clan Tralesta, altered to live for centuries so that she can kill every member of the rival clan Lornak, and Riker is finally forced to stop her.
