Rate main social works for Browning (14)

I believe the answer is:

caramelisation

'browning' is the definition.
(process that turns sugar brown)

'rate main social works' is the wordplay.
'works' indicates an anagram (work can mean to twist or convulse).
'rate'+'main'+'social'='ratemainsocial'
'ratemainsocial' anagrammed gives 'CARAMELISATION'.

'for' acts as a link.

I've seen this clue in The Telegraph.
