Accompaniments for dish: order smells terrible! (9)
I believe the answer is:
trimmings
'accompaniments' is the definition.
(I have seen 'Traditional accompaniments' mean 'trimmings' so perhaps 'accompaniments' could also mean 'trimmings')
'dish order smells terrible' is the wordplay.
I cannot quite understand how this works, but
'order' could be 'trim' (trim is a kind of order) and 'trim' is found in the answer.
The remaining letters 'mings' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for trimmings that I've seen before include "that are cut off" , "Traditional accompaniments" , "Accoutrements" .)
