There’s flavouring, I notice, inside and outside (7)
I believe the answer is:
aniseed
'there's flavouring' is the definition.
I can't judge whether this definition defines the answer.
'i notice inside and outside' is the wordplay.
'notice' becomes 'see' (notice can mean to spot or see).
'inside' indicates putting letters inside.
'outside' is an insertion indicator (some letters go outside others).
'see' going into 'and' is 'anseed'.
'i' going within 'anseed' is 'ANISEED'.
Can you help me to learn more?
(Other definitions for aniseed that I've seen before include "Aromatic flavouring" , "Liquorice-flavoured seeds" , "taste of Pernod, perhaps?" , "Licorice-flavoured sweets" , "Liquorice flavouring, used in cookery" .)
