A revolutionary force in the kitchen? (4)

Ross

I believe the answer is:

chef

I'm a little stuck... Click here to teach me more about this clue!

'the kitchen?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.

'a revolutionary force' is the wordplay.
'a revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'force' becomes 'F' (symbol used in Physics e.g. f=ma).
'che'+'f'='CHEF'

'in' is the link.

Can you help me to learn more?

(Other definitions for chef that I've seen before include "Kitchen head" , "Chief male cook in restaurant" , "member of kitchen staff" , "Head cook in a restaurant" , "Originator of courses" .)
