With drinks I notice flavouring of absinthe (7)
I believe the answer is:
aniseed
'flavouring of absinthe' is the definition.
'aniseed' can be an answer for 'flavouring' (I've seen this before). I am unsure of the 'of absinthe' bit.
'with drinks i notice' is the wordplay.
'with' becomes 'and'.
'drinks' means one lot of letters goes inside another (inserted letters are consumed or drunk).
'notice' becomes 'see' (notice can mean to spot or see).
'i'+'see'='isee'
'and' enclosing 'isee' is 'ANISEED'.
Can you help me to learn more?
(Other definitions for aniseed that I've seen before include "Liquorice flavouring, used in cookery" , "Plant" , "Liquorice flavour" , "Cake flavouring" , "Eased in (anag)" .)
