Boffin made this spicy concoction (9)
I believe the answer is:
physicist
'boffin' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'this spicy concoction' is the wordplay.
'concoction' indicates an anagram.
'this'+'spicy'='thisspicy'
'thisspicy' anagrammed gives 'PHYSICIST'.
'made' acts as a link.
Can you help me to learn more?
(Other definitions for physicist that I've seen before include "One studying the nature of matter" , "To become a scientist, doctor gets a name change to the street" , "Expert in the science of matter and energy" .)
