Professional in kitchen given revolutionary fine (4)
I believe the answer is:
chef
'professional in kitchen' is the definition.
'revolutionary fine' is the wordplay.
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'fine' becomes 'f' (abbreviation).
'che'+'f'='CHEF'
'given' is the link.
(Other definitions for chef that I've seen before include "Saucier" , "Key kitchen worker" , "Principal cook" , "Head cook in a restaurant" , "Hotel cook" .)
