Pleasant-sounding, cooking cod with lime (7)
I believe the answer is:
melodic
'pleasant-sounding' is the definition.
(I've seen this before)
'cooking cod with lime' is the wordplay.
'cooking' indicates an anagram (cook can mean to falsify or distort).
'with' means one lot of letters go next to another.
'cod' put after 'lime' is 'limecod'.
'limecod' with letters rearranged gives 'MELODIC'.
(Other definitions for melodic that I've seen before include "Harmonious" , "Of music, tuneful and sweet" , "nice on the ear" , "Pleasant-sounding" , "Pleasantly musical" .)
