Criticised cook and journalist (7)

Ross

I believe the answer is:

roasted

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

'criticised' is the definition.
Although both the answer and definition are past participle verbs, I can't understand how they can define each other.

'cook and journalist' is the wordplay.
'cook' becomes 'roast' (roasting is a kind of cooking).
'and' says to put letters next to each other.
'journalist' becomes 'ed' (short for editor).
'roast'+'ed'='ROASTED'

Can you help me to learn more?

(Other definitions for roasted that I've seen before include "Cooked (turkey?)" , "Severely reprimanded" , "Cooked hot food" , "Carpeted" , "Cooked (like a joint)" .)

I've seen this clue in The Mirror and The Daily Express.
