![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
coriander
(Other definitions for coriander that I've seen before include "Herb used with carrot for soup" , "ingredient of coronation chicken?" , "Parsley-like herb used in cooking" , "Aromatic herb" , "Carried on with the strange herb" .)
