Smell a long cured sausage (7)
I believe the answer is:
bologna
'sausage' is the definition.
(I know that bologna is a type of sausage)
'smell a long cured' is the wordplay.
'smell' becomes 'B.O.' (abbreviation for Body Odour).
'cured' is an anagram indicator.
'a'+'long'='along'
'along' anagrammed gives 'logna'.
'bo'+'logna'='BOLOGNA'
(Other definitions for bologna that I've seen before include "North Italian university city" , "Capital of Emilia-Romagna" , "Italian city - smoked sausage" , "Italian province" .)
