Herb used in pesto (5)

Ross

I believe the answer is:

basil

'herb used in pesto' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for basil that I've seen before include "Culinary plant" , "Herb - Mr Fawlty" , "named Cardinal Hume" , "Sweet-smelling herb" , "Herb of mint family" .)

I've seen this clue in the Sydney Morning Herald and The Guardian.
