Flavorful seed (6)
I believe the answer is:
sesame
'flavorful seed' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sesame that I've seen before include "Seed or oil used in cooking" , "Seeds used for making oil" , "Oil-producing plant" , "Password of the Arabian Nights" , "Oil-rich seed plant" .)
