With a tomato, little jerk is sweet-scented (8)
I believe the answer is:
aromatic
'sweet-scented' is the definition.
(I've seen this before)
'with a tomato little jerk' is the wordplay.
'with' means one lot of letters go next to another.
'a tomato' becomes 'aroma' (I can't justify this - if you can you should give a lot more credence to this answer).
'little jerk' becomes 'tic'.
'aroma' next to 'tic' is 'AROMATIC'.
'is' is the link.
Can you help me to learn more?
(Other definitions for aromatic that I've seen before include "giving out bouquet" , "Cairo mat may smell nice" , "with distinctive odour" , "Sweet-smelling, fragrant" , "Fragrant and spicey" .)
