City journalist, essentially stingy, rejected hot food (9)

I believe the answer is:

edinburgh

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

'city' is the definition.
(Edinburgh is an example)

'journalist essentially stingy rejected hot food' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'essentially' means to look at the middle letters.
'rejected hot food' becomes 'burgh' (I can't justify this - if you can you should believe this answer much more).
The central letters of 'stingy' are 'in'.
'ed'+'in'+'burgh'='EDINBURGH'

Can you help me to learn more?
