Insult by English copper journalist grilled (9)

I believe the answer is:

barbecued

'grilled' is the definition.
(barbecuing is a kind of grilling)

'insult by english copper journalist' is the wordplay.
'insult' becomes 'barb' (I've seen this before).
'by' means one lot of letters go next to another.
'english' becomes 'e' (abbreviation).
'copper' becomes 'cu' (chemical symbol).
'journalist' becomes 'ed' (short for editor).
'barb'+'e'+'cu'+'ed'='BARBECUED'

I've seen this clue in The Times.
