I look inside and find some flavouring (7)
I believe the answer is:
aniseed
'some flavouring' is the definition.
(I've seen this before)
'i look inside and' is the wordplay.
'look' becomes 'see'.
'inside' means one lot of letters goes inside another.
'i'+'see'='isee'
'isee' put into 'and' is 'ANISEED'.
'find' acts as a link.
(Other definitions for aniseed that I've seen before include "Pernod flavouring" , "taste of Pernod, perhaps?" , "Liquorice flavouring -- ie Danes (anag)" , "Eased in (anag)" , "Licorice-flavoured sweets" .)
