I believe the answer is:

maker

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

'producer' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for maker that I've seen before include "God Almighty" , "Fabricator; poet (arch.)" , "Producer" , "Manufacturer" , "Creator" .)

I've seen this clue in the Evening Standard.
