Cooled the unusually red fire grate (12)

I believe the answer is:

refrigerated

'cooled' is the definition.
(refrigerating is a kind of cooling)

'unusually red fire grate' is the wordplay.
'unusually' indicates anagramming the letters.
'red'+'fire'+'grate'='redfiregrate'
'redfiregrate' anagrammed gives 'REFRIGERATED'.

'the' acts as a link.

I've seen this clue in The Globe and Mail.
