Flavouring that makes money (4)
I believe the answer is:
mint
'flavouring' is the definition.
(mint is a kind of flavouring)
'money' is the wordplay.
I cannot quite see how this works, but
'money' could be 'm' (abbreviation used in economics) and 'm' is found within the answer.
The remaining letters 'int' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'that makes' is the link.
Can you help me to learn more?
(Other definitions for mint that I've seen before include "and 18 Down: Southern US cocktail" , "strongroom in treasury" , "Plant - in perfect condition" , "Building where coin money is made (4)" , "Fragrant herb" .)
