Fudge is wrong after starter of dumplings (7)
I believe the answer is:
distort
'fudge' is the definition.
(thesaurus)
'is wrong after starter of dumplings' is the wordplay.
'wrong' becomes 'tort' (a civil wrong in law).
'after' means one lot of letters go next to another.
'starter of' suggests taking the first letters.
The first letter of 'dumplings' is 'd'.
'is'+'tort'='istort'
'istort' after 'd' is 'DISTORT'.
(Other definitions for distort that I've seen before include "bend" , "Misrepresent" , "Warp" , "Deform" , "Get out of shape" .)
