Crossword Genius

Certain diet fine in the cooking (8)

Ross

I believe the answer is:

definite

'certain' is the definition.
(similar in meaning)

'diet fine in the cooking' is the wordplay.
'in the cooking' indicates an anagram (letters must be cooked or processed).
'diet'+'fine'='dietfine'
'dietfine' with letters rearranged gives 'DEFINITE'.

(Other definitions for definite that I've seen before include "Explicit, positive" , "Certain; clearly stated" , "Certain, decisive" , "The is the article" , "Clearly marked out" .)

I've seen this clue in The Sun.
