Cooks see, in amongst commercial packaging, some flavour (7)
I believe the answer is:
aniseed
'some flavour' is the definition.
(I've seen this before)
'cooks see in amongst commercial' is the wordplay.
'cooks' is an anagram indicator.
'amongst' indicates putting letters inside (I've seen this in other clues).
'commercial' becomes 'ad' (abbreviation for advertisement).
'see'+'in'='seein'
'seein' is an anagram of 'nisee'.
'nisee' going inside 'ad' is 'ANISEED'.
'packaging' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for aniseed that I've seen before include "Licorice-flavoured sweets" , "taste of Pernod, perhaps?" , "Natural flavouring" , "Liquorice flavour" , "Strong flavouring often used in sweets" .)
