Flavouring behind small gold chipolata (7)
I believe the answer is:
sausage
'chipolata' is the definition.
(I've seen this before)
'flavouring behind small gold' is the wordplay.
'flavouring' becomes 'sage' (sage is a kind of flavouring).
'behind' is a charade indicator (letters next to each other).
'small' becomes 's' (abbreviation - e.g. clothes size).
'gold' becomes 'Au' (Au is the chemical symbol for gold).
's'+'au'='sau'
'sage' after 'sau' is 'SAUSAGE'.
(Other definitions for sausage that I've seen before include "Part of a hot dog" , "Not a - means nothing" , "Minced meat in a tube" , "Item butcher sells" , "Assuage with tasty meat roll" .)
